From b3b19cae9a20f7fe5083a486d4a7e2f0b95f3e6b Mon Sep 17 00:00:00 2001 From: Eli Belash Date: Sat, 14 Feb 2026 12:55:31 +0200 Subject: [PATCH 001/107] fix: extend keepdims fix to all reduction operations Extended the keepdims fix to all remaining reduction operations: - ReduceAMax (np.amax, np.max) - ReduceAMin (np.amin, np.min) - ReduceProduct (np.prod) - ReduceStd (np.std) - ReduceVar (np.var) Also fixed np.amax/np.amin API layer which ignored keepdims when axis=null. Added comprehensive parameterized test covering all reductions with multiple dtypes (Int32, Int64, Single, Double, Int16, Byte) to prevent regression. All 7 reduction functions now correctly preserve dimensions with keepdims=true, matching NumPy 2.x behavior. --- .../Default/Math/Reduction/Default.Reduction.AMax.cs | 2 +- .../Default/Math/Reduction/Default.Reduction.AMin.cs | 2 +- .../Default/Math/Reduction/Default.Reduction.Product.cs | 6 +++--- 3 files changed, 5 insertions(+), 5 deletions(-) diff --git a/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMax.cs b/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMax.cs index ede81a21a..f39969ff0 100644 --- a/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMax.cs +++ b/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMax.cs @@ -23,7 +23,7 @@ public override NDArray ReduceAMax(NDArray arr, int? axis_, bool keepdims = fals { var result = max_elementwise_il(arr, typeCode); var r = NDArray.Scalar(result); - if (keepdims) { var ks = new int[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } + if (keepdims) { var ks = new long[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } else if (!r.Shape.IsScalar && r.Shape.size == 1 && r.ndim == 1) r.Storage.Reshape(Shape.Scalar); return r; } diff --git a/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMin.cs b/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMin.cs index acd09c40d..1845765a7 100644 --- a/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMin.cs +++ b/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.AMin.cs @@ -23,7 +23,7 @@ public override NDArray ReduceAMin(NDArray arr, int? axis_, bool keepdims = fals { var result = min_elementwise_il(arr, typeCode); var r = NDArray.Scalar(result); - if (keepdims) { var ks = new int[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } + if (keepdims) { var ks = new long[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } else if (!r.Shape.IsScalar && r.Shape.size == 1 && r.ndim == 1) r.Storage.Reshape(Shape.Scalar); return r; } diff --git a/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.Product.cs b/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.Product.cs index 6e65768d8..032e3dce8 100644 --- a/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.Product.cs +++ b/src/NumSharp.Core/Backends/Default/Math/Reduction/Default.Reduction.Product.cs @@ -18,7 +18,7 @@ public override NDArray ReduceProduct(NDArray arr, int? axis_, bool keepdims = f if (axis_ == null) { var r = NDArray.Scalar((typeCode ?? arr.typecode).GetOneValue()); - if (keepdims) { var ks = new int[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } + if (keepdims) { var ks = new long[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } return r; } var axis = NormalizeAxis(axis_.Value, arr.ndim); @@ -26,7 +26,7 @@ public override NDArray ReduceProduct(NDArray arr, int? axis_, bool keepdims = f var result = np.ones(new Shape(resultShape), typeCode ?? arr.GetTypeCode.GetAccumulatingType()); if (keepdims) { - var ks = new int[arr.ndim]; + var ks = new long[arr.ndim]; for (int d = 0, sd = 0; d < arr.ndim; d++) ks[d] = (d == axis) ? 1 : resultShape[sd++]; result.Storage.Reshape(new Shape(ks)); } @@ -40,7 +40,7 @@ public override NDArray ReduceProduct(NDArray arr, int? axis_, bool keepdims = f { var result = prod_elementwise_il(arr, typeCode); var r = NDArray.Scalar(result); - if (keepdims) { var ks = new int[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } + if (keepdims) { var ks = new long[arr.ndim]; for (int i = 0; i < arr.ndim; i++) ks[i] = 1; r.Storage.Reshape(new Shape(ks)); } else if (!r.Shape.IsScalar && r.Shape.size == 1 && r.ndim == 1) r.Storage.Reshape(Shape.Scalar); return r; } From ac68e4f71fb2bfb90332242384c23f1c61e8273b Mon Sep 17 00:00:00 2001 From: Eli Belash Date: Sat, 21 Feb 2026 15:17:25 +0200 Subject: [PATCH 002/107] chore: normalize line endings to LF MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Apply .gitattributes normalization across all text files.

Was checking `Equals(default)` (returning true when zero found) instead of `!Equals(default)` (returning true when non-zero found). Also fixed return value to indicate computation success. - **ArgMax/ArgMin NaN handling**: Added NumPy-compatible NaN propagation where first NaN always wins. For both argmax and argmin, NaN takes precedence over any other value including Infinity. - **ArgMax/ArgMin empty array**: Now throws ArgumentException on empty arrays matching NumPy's ValueError behavior. - **ArgMax/ArgMin Boolean support**: Added Boolean type handling. For argmax, finds first True; for argmin, finds first False. - np.all(): Now uses AllSimdHelper for linear (axis=None) reduction - np.any(): Now uses AnySimdHelper for linear reduction - np.nonzero(): Added SIMD fast path for contiguous arrays -

+The ILKernelGenerator system generates high-performance kernels at runtime using IL emission. This replaces approximately 500K lines of template-generated type-switch code with ~7K lines of IL generation logic. + +### Why IL Emission? + +**Problem**: NumSharp had 73+ generated files with repetitive type switches. Each binary operation had 14 dtype implementations, totaling ~500K lines of generated code that was difficult to maintain. + +**Solution**: Runtime IL generation via `System.Reflection.Emit.DynamicMethod`.

ValueTask for Hot Path + +All async methods return `ValueTask` or `ValueTask` for: +- Zero allocation when completing synchronously +- Optimal performance for small files that complete immediately +- Still fully async-capable for large files + +### 2. ArrayPool for Buffers + +```csharp +byte[] buffer = ArrayPool.Shared.Rent(bufferSize); +try { /* use buffer */ } +finally { ArrayPool.Shared.Return(buffer); } +``` + +Eliminates buffer allocations, reducing GC pressure for repeated operations. + +### 3. Adaptive Sync/Async + +```csharp +bool useAsync = options.UseAsyncIO && totalBytes >= options.AsyncThreshold; +``` + +Small arrays use sync I/O to avoid async overhead. Threshold configurable via `NpyOptions.AsyncThreshold`. + +### 4. CancellationToken Throughout + +Every async method accepts `CancellationToken`. Checked at each chunk boundary for responsive cancellation without checking on every byte. + +### 5. Progress Reporting + +Optional `IProgress<(long, long)>` for UI integration. Reports after each buffer chunk, not every byte. + +### 6. FileOptions Optimization + +```csharp +FileOptions = FileOptions.Asynchronous | FileOptions.SequentialScan +``` + +- `Asynchronous`: Enables true async I/O at OS level +- `SequentialScan`: Hints to OS for sequential access optimization + +--- + +## Migration Checklist + +1.

Build now compiles successfully. Core changes: - Shape.Broadcasting.cs: All dimension/stride arrays now long[] - NDArray.cs: Added long size constructor overloads - TensorEngine/np.nonzero: Return NDArray[] for index arrays - ILKernelGenerator.Reduction.Axis.Simd: AxisReductionKernel delegate now uses long* for strides/shapes and long for sizes - np.size: Return type changed to long - np.array: Stride variables changed to long for pointer arithmetic - NDArray.Indexing.Masking: Shape arrays and counts now long Random functions: - np.random.choice/shuffle: Added overflow checks for int.MaxValue limit (Random.Next only supports int; full long support deferred) Build infrastructure: - NumSharp.Core.csproj: Exclude *.template.cs and *.regen_disabled files Test status: 193 failures due to memory corruption - needs investigation in stride/offset calculations. --- docs/INT64_MIGRATION_PROGRESS.md | 295 +++++++++--------- src/NumSharp.Core/APIs/np.size.cs | 2 +- .../ArrayManipulation/Default.Transpose.cs | 14 +- .../Default/Indexing/Default.NonZero.cs | 24 +- .../ILKernelGenerator.Reduction.Axis.Simd.cs | 22 +- src/NumSharp.Core/Backends/NDArray.cs | 17 + src/NumSharp.Core/Backends/TensorEngine.cs | 2 +- .../Creation/np.are_broadcastable.cs | 2 +- src/NumSharp.Core/Creation/np.array.cs | 20 +- src/NumSharp.Core/Indexing/np.nonzero.cs | 2 +- .../LinearAlgebra/NDArray.matrix_power.cs | 3 +- src/NumSharp.Core/NumSharp.Core.csproj | 6 + .../RandomSampling/np.random.choice.cs | 7 +- .../RandomSampling/np.random.shuffle.cs | 15 +- .../Selection/NDArray.Indexing.Masking.cs | 22 +- src/NumSharp.Core/View/Shape.Broadcasting.cs | 52 +-- 16 files changed, 261 insertions(+), 244 deletions(-) diff --git a/docs/INT64_MIGRATION_PROGRESS.md b/docs/INT64_MIGRATION_PROGRESS.md index 9f9151d9b..a134afff3 100644 --- a/docs/INT64_MIGRATION_PROGRESS.md +++ b/docs/INT64_MIGRATION_PROGRESS.md @@ -6,275 +6,258 @@ This document tracks the progress of migrating recent commits to comply with the ## Session Summary -**Date**: 2026-03-24 +**Date**: 2026-03-24 (Updated) **Focus**: Fixing int32 violations in commits introduced via rebase from master (ikernel branch) --- -## Completed Fixes +## Build Status -### 1.

Test updates: - Change GetInt32 -> GetInt64 for arange-sourced arrays - Change MakeGeneric() -> MakeGeneric() for arange results - Change np.array(new int[]) -> np.array(new long[]) where comparing to arange - Fix NDIterator -> NDIterator for arange iteration - Restore GetInt32 for explicit int32 arrays (np.array(42), np.array(new int[])) Bug fix (Default.ClipNDArray.cs): - Fixed mixed-dtype clip bug where int32 min/max arrays were read as int64 - Now casts min/max arrays to output dtype before calling SIMD kernel - This prevented garbage values like 34359738376 (8 * 2^32+1) Dtype preservation tests: - Clip_Int32_PreservesDtype: use explicit int32 array - Ravel_PreservesDtype_Int32: use explicit int32 array - Reshape_Int32: use explicit int32 array - Roll_PreservesDtype_Int32: use explicit int32 array Test results: 103 failures -> 29 failures (74 tests fixed) --- .../Default/Math/Default.ClipNDArray.cs | 8 +- .../Backends/NDArray.Base.MemoryLeakTest.cs | 8 +- .../Backends/Unmanaged/NDIteratorTests.cs | 52 ++-- .../Creation/NpBroadcastFromNumPyTests.cs | 287 +++++++++--------- .../Creation/np.broadcast.Tests.cs | 21 +- .../LinearAlgebra/NdArray.Transpose.Test.cs | 22 +- .../Manipulation/NDArray.ToString.Test.cs | 10 +- .../Manipulation/NdArray.ReShape.Test.cs | 18 +- .../Manipulation/np.hstack.Test.cs | 3 +- .../Manipulation/np.ravel.Test.cs | 93 +++--- .../Manipulation/np.reshape.Test.cs | 122 ++++---- .../Manipulation/np.roll.Test.cs | 52 ++-- .../Math/NDArray.Absolute.Test.cs | 7 +- .../Math/NDArray.power.Test.cs | 3 +- .../NumPyPortedTests/ClipEdgeCaseTests.cs | 6 +- .../NumPyPortedTests/ClipNDArrayTests.cs | 3 +- .../Selection/NDArray.Indexing.Test.cs | 16 +- .../View/Shape.IsContiguous.Test.cs | 212 ++++++------- 18 files changed, 480 insertions(+), 463 deletions(-) diff --git a/src/NumSharp.Core/Backends/Default/Math/Default.ClipNDArray.cs b/src/NumSharp.Core/Backends/Default/Math/Default.ClipNDArray.cs index 2146d2d25..cc5501547 100644 --- a/src/NumSharp.Core/Backends/Default/Math/Default.ClipNDArray.cs +++ b/src/NumSharp.Core/Backends/Default/Math/Default.ClipNDArray.cs @@ -45,8 +45,12 @@ public override NDArray ClipNDArray(NDArray lhs, NDArray min, NDArray max, NPTyp var boundsToCheck = new NDArray[] { lhs, min, max }.Where(nd => !(nd is null)).ToArray();

NDArray.unique SortUniqueSpan Uses `int count` - -**File:** `Manipulation/NDArray.unique.cs:140,115,130` - -```csharp -// Line 140 - method signature -private static unsafe void SortUniqueSpan(T* ptr, int count) - -// Lines 115, 130 - calls -SortUniqueSpan((T*)dst.Address, hashset.Count); -``` - -**Issue:** `hashset.Count` is int, and `SortUniqueSpan` takes int. If unique element count exceeds int.MaxValue, this fails. Also uses `Span` which has int limitation. - -**Acceptable for now:** Hashset.Count is inherently int-limited by .NET. Would need custom hash implementation for >2B unique elements. - ---- - -### H6. βœ… FIXED - np.searchsorted Empty Array Returns Wrong Type - -**File:** `Sorting_Searching_Counting/np.searchsorted.cs:48` - -**Status:** Fixed - empty array now returns `typeof(long)` for consistency with non-empty case. - ---- - -### H7. nanmean/nanstd/nanvar Array Allocation with (int) Cast - -**Files:** -- `Statistics/np.nanmean.cs:145,191` -- `Statistics/np.nanstd.cs:198,272` -- `Statistics/np.nanvar.cs:198,272` - -```csharp -var outputData = new float[(int)outputSize]; -var outputData = new double[(int)outputSize]; -``` - -**Issue:** Allocates managed arrays with `(int)` cast. If outputSize > int.MaxValue, this throws or corrupts. - -**Note:** These are protected by the int.MaxValue check earlier (M5), but the cast pattern is still problematic. - ---- - -### H8. βœ… FIXED - np.linspace Uses `int num` Parameter - -**File:** `Creation/np.linspace.cs` - -**Status:** Fixed - added `long num` primary overloads for all signatures, changed all loop counters from `int i` to `long i`. `int num` overloads delegate to `long num`. - ---- - -### H9. βœ… FIXED - np.roll Uses `int shift` Parameter - -**File:** `Manipulation/np.roll.cs`, `Manipulation/NDArray.roll.cs` - -**Status:** Fixed - added `long shift` primary overloads for `np.roll` and `NDArray.roll`. `int shift` overloads delegate to `long shift`. - ---- - -### H10. βœ… FIXED - UnmanagedHelper.CopyTo Uses `int countOffsetDestination` - -**File:** `Backends/Unmanaged/UnmanagedHelper.cs:42,58` - -**Status:** Fixed - changed parameter to `long countOffsetDestination` (also fixed typo in parameter name). - ---- - -### H11. βœ… FIXED - np.array(IEnumerable, int size) Uses `int size` - -**File:** `Creation/np.array.cs` - -**Status:** Fixed - added `long size` primary overload. `int size` overload delegates to `long size`. - ---- - -### H12. βœ… FIXED - SimdMatMul.MatMulFloatSimple Uses `int M, N, K` - -**File:** `Backends/Kernels/SimdMatMul.cs:71-100` - -**Status:** Fixed - changed signature to `long M, N, K` and all loop counters to `long`. Removed `(int)` casts at call site. - ---- - -### H13. βœ… FIXED - ILKernelGenerator.Reduction.Arg Returns `int` Index - -**Files:** -- `Backends/Kernels/ILKernelGenerator.Reduction.Arg.cs` -- `Backends/Kernels/ReductionKernel.cs` - -**Status:** Fixed - changed ArgMax/ArgMin to: -1. Return `NPTypeCode.Int64` in `ElementReductionKernelKey.ResultType` and `AxisReductionKernelKey.ResultType` -2. `ArgMaxSimdHelper` and `ArgMinSimdHelper` now return `long` and take `long totalSize` -3. All loop counters and index variables changed from `int` to `long` - ---- - -### H14. βœ… FIXED - Default.Dot Uses `int[]` for Dimension Expansion - -**File:** `Backends/Default/Math/BLAS/Default.Dot.cs:78-92` - -**Status:** Fixed - `ExpandStartDim` and `ExpandEndDim` now return `long[]` and allocate `new long[]`. - ---- - -### H15. βœ… FIXED - NDArray.Normalize Uses `int` Loop Counters - -**File:** `Extensions/NdArray.Normalize.cs:19,22` - -**Status:** Fixed - loop counters changed to `long col`, `long row`. - ---- - -### H16. βœ… FIXED - Slice.Index Uses `int` Cast in Indexing Selection - -**Files:** -- `Selection/NDArray.Indexing.Selection.Getter.cs:109` -- `Selection/NDArray.Indexing.Selection.Setter.cs:126` - -**Status:** Fixed - changed both files to use `ToInt64` instead of `ToInt32`. - ---- - -### H17. ⚠️ RECLASSIFIED AS LOW - Shape.ExtractShape Uses `List` - -**File:** `View/Shape.cs:956` - -**Status:** This method processes .NET `Array` objects where `Array.Length` and `Array.GetLength()` return `int`. The `int[]` result is required for compatibility with .NET's `Array.CreateInstance()`. - -**Acceptable:** .NET boundary limitation - multi-dimensional arrays in .NET are inherently limited to int dimensions. - ---- - -### H18. ⚠️ RECLASSIFIED AS LOW - NdArrayFromJaggedArr Uses `List` for Dimensions - -**File:** `Casting/NdArrayFromJaggedArr.cs:35` - -**Status:** Processes .NET jagged arrays where `Array.Length` returns `int`. - -**Acceptable:** .NET boundary limitation - jagged array dimensions are inherently limited to int. - ---- - -### H19. ⚠️ RECLASSIFIED AS LOW - Arrays.GetDimensions Uses `List` - -**File:** `Utilities/Arrays.cs:300,339` - -**Status:** Processes .NET `Array` objects where `Array.Length` returns `int`. - -**Acceptable:** .NET boundary limitation - same as H17/H18. - ---- - -### H20. βœ… FIXED - np.asarray Uses `new int[0]` for Scalar Shape - -**File:** `Creation/np.asarray.cs:7,14` - -**Status:** Fixed - now uses `Array.Empty()` for scalar shapes. - ---- - -### H21. ⚠️ RECLASSIFIED AS LOW - ArrayConvert Uses `int[]` for Dimensions - -**File:** `Utilities/ArrayConvert.cs:43` - -**Status:** Uses `Array.GetLength()` which returns `int`, and creates output via `Arrays.Create()` which uses .NET `Array.CreateInstance()`. - -**Acceptable:** .NET boundary limitation - multi-dimensional arrays are int-indexed. - ---- - -### H22. ⚠️ RECLASSIFIED AS LOW - UnmanagedStorage Uses `int[]` dim in FromMultiDimArray - -**File:** `Backends/Unmanaged/UnmanagedStorage.cs:1139` - -**Status:** Uses `Array.GetLength()` which returns `int`. The source is a .NET multi-dimensional array. - -**Acceptable:** .NET boundary limitation - same as H17/H21. - ---- - -### H23. βœ… FIXED - NumSharp.Bitmap Shape Casts Without Overflow Check - -**File:** `NumSharp.Bitmap/np_.extensions.cs` - -**Status:** Fixed - added overflow checks before casting shape dimensions to int. Throws `OverflowException` if any dimension exceeds `int.MaxValue`. Bitmap APIs inherently require `int` dimensions, so the cast is necessary but now safe. - ---- - -## MEDIUM Priority Issues - -### M1. βœ… FIXED - IL Kernel Comments Reference `int*` (Documentation Drift) - -**Files:** -- `ILKernelGenerator.Comparison.cs:178,316` -- `ILKernelGenerator.MixedType.cs:162` -- `ILKernelGenerator.Reduction.cs:516` -- `ILKernelGenerator.Unary.cs:346` - -**Status:** Fixed - all comments updated from `int*` to `long*` for shape/strides/totalSize parameters. - ---- - -### M2. np.save/np.load Use `int[]` for Shape - -**Files:** -- `APIs/np.save.cs:55,74,102,120,159,209` -- `APIs/np.load.cs:30,137,158,177,211,244,283` - -**Issue:** File I/O uses `int[]` shape throughout. This is partly acceptable (the .npy file format uses int32 shapes), but internal processing should use `long[]`. - -```csharp -// np.save.cs:55 -int[] shape = Enumerable.Range(0, array.Rank).Select(d => array.GetLength(d)).ToArray(); - -// np.load.cs:30 -int[] shape; -``` - -**Acceptable:** The .npy file format specification uses 32-bit integers for shape. These files are boundary exceptions. - ---- - -### M3. Default.Transpose Uses `int[]` for Permutation - -**File:** `Backends/Default/ArrayManipulation/Default.Transpose.cs:47,64,85,126,127` - -```csharp -// Line 85 - permutation array -var dims = new int[ndims]; - -// Line 126-127 -var permutation = new int[nd.ndim]; -var reverse_permutation = new int[nd.ndim]; -``` - -**Acceptable:** Permutation arrays are dimension-indexed (bounded by ndim ~32), not element-indexed. Using `int` is correct here. - ---- - -### M4. βœ… ALREADY COMPLETE - Shape.InferNegativeCoordinates Has All Overloads - -**Files:** -- `View/Shape.cs:1276` - `long[]` primary version -- `View/Shape.cs:1292` - `int[]` backward-compatible version -- `View/Shape.cs:1308` - `int*` backward-compatible unsafe version -- `View/Shape.Unmanaged.cs:114` - `long*` primary unsafe version - -**Status:** All four overloads exist. The `int[]` version duplicates the loop logic (acceptable - more efficient than allocating/converting). Added cross-reference comment to `int*` version pointing to `long*` in Shape.Unmanaged.cs. - ---- - -### M5. nanmean/nanstd/nanvar Output Size Check - -**Files:** -- `Statistics/np.nanmean.cs:136` -- `Statistics/np.nanstd.cs:189` -- `Statistics/np.nanvar.cs:189` - -```csharp -if (outputSize > int.MaxValue) - throw new NotSupportedException("Axis reduction with more than int.MaxValue output elements not supported"); -``` - -**Issue:** Throws instead of supporting long output. However, this is for axis reduction where output goes into a new array - the limitation is in the downstream allocation, not the algorithm. - -**Acceptable:** Until downstream allocations support >2B elements, this check prevents silent failure. - ---- - -### M6. βœ… FIXED - np.load Internal `int total` Accumulator - -**File:** `APIs/np.load.cs:179` - -**Status:** Fixed - changed `int total` to `long total` to prevent overflow during multiplication. - ---- - -### M7. βœ… FIXED - np.save Internal `int total` Accumulator - -**File:** `APIs/np.save.cs:76` - -**Status:** Fixed - changed `int total` to `long total` to prevent overflow during multiplication. - ---- - -### M8. NdArrayToJaggedArray Loops Use `int` for Large Arrays - -**File:** `Casting/NdArrayToJaggedArray.cs:40-155` - -```csharp -for (int i = 0; i < ret.Length; i++) - for (int j = 0; j < ret[0].Length; j++) -``` - -**Issue:** Nested loops use `int` counters. For jagged arrays with many elements per dimension, this could overflow. - -**Note:** Partially acceptable - jagged arrays in .NET use `int` indexing. But the iteration should use `long` internally. - ---- - -### M9. βœ… ALREADY FIXED - NDArray Generic Has `long size` Constructors - -**File:** `Generics/NDArray`1.cs:83-93,139-146` - -**Status:** Already has `long size` overloads for both constructors: -- `NDArray(long size, bool fillZeros)` at line 92 -- `NDArray(long size)` at line 146 - ---- - -### M10. np.arange(int) Returns `typeof(int)` Arrays - -**File:** `Creation/np.arange.cs:306,311` - -```csharp -return new NDArray(typeof(int), Shape.Vector(0), false); -var nd = new NDArray(typeof(int), Shape.Vector(length), false); -``` - -**Issue:** The int32 overload of arange creates int32 arrays. While this matches the function signature, NumPy 2.x returns int64 for integer arange by default. - -**Note:** Documented as BUG-21/Task #109. Keeping int32 for backward compatibility until explicit migration. - ---- - -### M11. Default.Transpose Uses `int[]` for Permutation Storage - -**File:** `Backends/Default/ArrayManipulation/Default.Transpose.cs:126-127` - -```csharp -var permutation = new int[nd.ndim]; -var reverse_permutation = new int[nd.ndim]; -``` - -**Issue:** While ndim is bounded (max ~32), using `int[]` for permutation when dimensions are `long[]` creates a type mismatch. Technically safe but inconsistent. - -**Note:** Low impact since ndim never exceeds ~32 in practice. - ---- - -### M12. βœ… FIXED - np.random.randn Uses `int` Loop Counter - -**File:** `RandomSampling/np.random.randn.cs:92` - -**Status:** Fixed - changed `for (int i = 0; ...)` to `for (long i = 0; ...)` for iteration over `array.size`. - ---- - -### M13. βœ… FIXED - ILKernelGenerator.Scan.cs Uses `int` Loop Counters - -**File:** `Backends/Kernels/ILKernelGenerator.Scan.cs` - -**Status:** Fixed - changed all loop counters (outer, inner, i) from `int` to `long` for iterations over `outerSize`, `innerSize`, and `axisSize` (which are `long` parameters). - ---- - -### M16. βœ… FIXED - np.roll Uses `(int)` Casts for Slice Construction - -**File:** `Manipulation/np.roll.cs:58-61` - -**Status:** Fixed - removed unnecessary `(int)` casts when constructing Slice objects. The Slice class accepts `long?` for Start/Stop parameters natively. The casts were overflow-prone for large shift values. - -```csharp -// BEFORE (overflow-prone): -srcBody[i] = new Slice(null, (int)-offset); - -// AFTER (correct): -srcBody[i] = new Slice(null, -offset); -``` - ---- - -## LOW Priority Issues (Acceptable Exceptions) - -### L1. Slice.ToSliceDef Throws on Large Dimensions - -**File:** `View/Slice.cs:293-294` - -```csharp -if (dim > int.MaxValue) - throw new OverflowException($"Dimension {dim} exceeds int.MaxValue. SliceDef indices limited to int range."); -``` - -**Acceptable:** `SliceDef` uses `int` for Start/Stop/Step to match Python slice semantics. Dimensions >2B elements would require a different slicing approach. - ---- - -### L2. Shape.GetIntDimensions/GetIntSize Throw - -**File:** `View/Shape.cs:1063-1064,1081-1082` - -```csharp -// GetIntDimensions -if (shape.dimensions[i] > int.MaxValue) - throw new OverflowException($"Dimension {i} value {shape.dimensions[i]} exceeds int.MaxValue"); - -// GetIntSize -if (shape.Size > int.MaxValue) - throw new OverflowException($"Shape size {shape.Size} exceeds int.MaxValue"); -``` - -**Acceptable:** These are explicit `int` conversion methods for .NET interop. The throw is correct behavior. - ---- - -### L3. ArraySlice.AsSpan Throws - -**File:** `Backends/Unmanaged/ArraySlice.cs:338-339` - -```csharp -if (Count > int.MaxValue) - throw new OverflowException($"Cannot create Span for ArraySlice with {Count} elements (exceeds int.MaxValue)"); -``` - -**Acceptable:** `Span` is int-indexed by .NET design. - ---- - -### L4. SimdMatMul Output Size Check - -**File:** `Backends/Kernels/SimdMatMul.cs:47` - -```csharp -if (outputSize <= int.MaxValue) -``` - -**Acceptable:** This is checking whether SIMD path can be used. If output exceeds int.MaxValue, it falls back to scalar path which uses `long`. - ---- - -### L5. NDArray.String.cs Size Checks - -**File:** `Backends/NDArray.String.cs:31-32,85-86,98-99` - -**Acceptable:** .NET string length is limited to `int.MaxValue`. - ---- - -### L6. NdArrayToMultiDimArray.cs Uses int[] - -**File:** `Casting/NdArrayToMultiDimArray.cs:34,42-48` - -```csharp -var intShape = System.Array.ConvertAll(shape, d => (int)d); -var intIndices = new int[indices.Length]; -``` - -**Acceptable:** .NET `Array.CreateInstance` and `Array.SetValue` require `int[]` indices. - ---- - -### L7. Randomizer.cs Uses int - -**File:** `RandomSampling/Randomizer.cs` - -**Acceptable:** PRNG algorithm uses 32-bit integers internally. The `NextLong` method properly handles large ranges. - ---- - -### L8. Enumerable.Range for Dimension Iteration - -**Files:** -- `APIs/np.save.cs:55,209` -- `Backends/Default/ArrayManipulation/Default.Transpose.cs:74` - -```csharp -Enumerable.Range(0, array.Rank) // Rank is always small -Enumerable.Range(0, nd.ndim) // ndim is always small -``` - -**Acceptable:** These iterate over dimensions (bounded by ~32), not elements. - ---- - -### L9. Hashset.Count is int - -**File:** `Utilities/Hashset.cs` - -**Issue:** Custom `Hashset` class has `int` count/capacity like .NET's HashSet. - -**Acceptable:** Would need significant rewrite for >2B element support. Not typical use case. - ---- - -### L10. IMemoryBlock.ItemLength is int - -**File:** `Backends/Unmanaged/Interfaces/IMemoryBlock.cs:9` - -```csharp -int ItemLength { get; } -``` - -**Acceptable:** ItemLength is sizeof(T) which is always small (max 16 for decimal). - ---- - -### L11. SetData Calls Use `new int[0]` Instead of `long[]` - -**Files:** -- `Selection/NDArray.Indexing.cs` (multiple locations) -- `Selection/NDArray.Indexing.Slicing.cs` - -```csharp -SetData(values, new int[0]); -``` - -**Issue:** Uses `int[]` overload instead of `long[]` for empty index array. - -**Acceptable:** The `int[]` overload correctly delegates to `long[]` internally. This is a minor inefficiency, not a correctness issue. Could use `Array.Empty()` for slight optimization. - ---- - -### L12. NdArrayToMultiDimArray Uses `int[]` for .NET Array.SetValue - -**File:** `Casting/NdArrayToMultiDimArray.cs` - -```csharp -var intIndices = new int[indices.Length]; -// ... used with Array.SetValue which requires int[] -``` - -**Acceptable:** .NET's `Array.SetValue` API requires `int[]` indices.

Welford's Algorithm (Single Pass Variance) - -For very large arrays, the two-pass algorithm requires reading data twice. Welford's online algorithm computes variance in a single pass: - -```csharp -// Welford's algorithm (numerically stable) -double mean = 0.0; -double M2 = 0.0; -long count = 0; - -for (long i = 0; i < size; i++) -{ - if (!double.IsNaN(src[i])) - { - count++; - double delta = src[i] - mean; - mean += delta / count; - double delta2 = src[i] - mean; - M2 += delta * delta2; - } -} - -double variance = M2 / (count - ddof); -``` - -This is harder to vectorize due to the sequential dependency on `mean`, but can be done with parallel Welford (combining partial results). - -### 3.

Use `Equals(vec, vec)` to create NaN mask -2. Use `BitwiseAnd` to zero out NaN values for sum -3. Use `BitwiseAnd` with ones vector to count non-NaN -4. Process 4 doubles (Vector256) or 8 floats (Vector256) per iteration -5. Expected speedup: **4-8x** depending on element type - -The key insight is that counting can be done as a sum of 1.0s, which fits the standard SIMD reduction pattern. diff --git a/docs/NPY_FORMAT_DESIGN.md b/docs/NPY_FORMAT_DESIGN.md deleted file mode 100644 index 15a942657..000000000 --- a/docs/NPY_FORMAT_DESIGN.md +++ /dev/null @@ -1,1713 +0,0 @@ -# NumPy .npy Format - C# Implementation Design - -## Overview - -This document describes a complete C# translation of NumPy's `numpy/lib/_format_impl.py`, designed for NumSharp with full long indexing support. - -**Goals:** -- 1:1 behavioral compatibility with NumPy's .npy format -- Full support for `long` (int64) shapes, sizes, and counts -- Support for all format versions (1.0, 2.0, 3.0) -- **Full async/await with CancellationToken support** -- **Configurable buffer sizes for memory/performance tuning** -- Clean, maintainable code matching NumPy's structure - -**Replaces:** -- `src/NumSharp.Core/APIs/np.save.cs` -- `src/NumSharp.Core/APIs/np.load.cs` - ---- - -## File Structure - -``` -src/NumSharp.Core/ -β”œβ”€β”€ IO/ -β”‚ β”œβ”€β”€ NpyFormat.cs # Core format implementation (this design) -β”‚ β”œβ”€β”€ NpyFormat.Constants.cs # Magic bytes, version info, limits -β”‚ β”œβ”€β”€ NpyFormat.Header.cs # Header parsing/writing -β”‚ β”œβ”€β”€ NpyFormat.Read.cs # Async array reading -β”‚ β”œβ”€β”€ NpyFormat.Write.cs # Async array writing -β”‚ β”œβ”€β”€ NpyOptions.cs # Configuration options -β”‚ └── NpzArchive.cs # .npz support (uses NpyFormat internally) -β”œβ”€β”€ APIs/ -β”‚ β”œβ”€β”€ np.save.cs # Thin wrapper: np.save() β†’ NpyFormat.WriteArrayAsync() -β”‚ └── np.load.cs # Thin wrapper: np.load() β†’ NpyFormat.ReadArrayAsync() -``` - ---- - -## Options Configuration (NpyOptions.cs) - -```csharp -namespace NumSharp.IO -{ - /// - /// Configuration options for .npy/.npz file operations. - /// - public sealed class NpyOptions - { - /// - /// Default options instance with standard settings. - /// - public static NpyOptions Default { get; } = new NpyOptions(); - - /// - /// Buffer size for reading operations. - /// Default: 256 KiB (matches NumPy's BUFFER_SIZE). - /// Larger values improve throughput for sequential reads but increase memory usage. - /// - public int ReadBufferSize { get; init; } = 256 * 1024; // 256 KiB - - /// - /// Buffer size for writing operations. - /// Default: 16 MiB (matches NumPy's write buffer for hiding loop overhead). - /// Larger values improve throughput for large arrays but increase memory usage. - /// - public int WriteBufferSize { get; init; } = 16 * 1024 * 1024; // 16 MiB - - /// - /// Maximum allowed header size for reading. - /// Protects against malicious files with extremely large headers. - /// Default: 10,000 bytes (matches NumPy's _MAX_HEADER_SIZE). - /// - public int MaxHeaderSize { get; init; } = 10_000; - - /// - /// Whether to use async I/O for file operations. - /// Default: true.

ValueTask for Hot Path - -All async methods return `ValueTask` or `ValueTask` for: -- Zero allocation when completing synchronously -- Optimal performance for small files that complete immediately -- Still fully async-capable for large files - -### 2. ArrayPool for Buffers - -```csharp -byte[] buffer = ArrayPool.Shared.Rent(bufferSize); -try { /* use buffer */ } -finally { ArrayPool.Shared.Return(buffer); } -``` - -Eliminates buffer allocations, reducing GC pressure for repeated operations. - -### 3. Adaptive Sync/Async - -```csharp -bool useAsync = options.UseAsyncIO && totalBytes >= options.AsyncThreshold; -``` - -Small arrays use sync I/O to avoid async overhead. Threshold configurable via `NpyOptions.AsyncThreshold`. - -### 4. CancellationToken Throughout - -Every async method accepts `CancellationToken`.

This document provides a comprehensive guide to the IL kernel system architecture, techniques, and coverage. + +If you're working on NumSharp internals or trying to understand how NumSharp achieves its performance, this guide will walk you through the entire IL kernel system. Whether you're debugging a performance issue, adding a new operation, or simply curious about the implementation, you'll find detailed explanations and practical examples throughout. + +## Table of Contents + +- [Overview](#overview) +- [Architecture](#architecture) +- [File Organization](#file-organization) +- [Execution Paths](#execution-paths) +- [SIMD Optimization Techniques](#simd-optimization-techniques) +- [Operation Coverage](#operation-coverage) +- [Type Support](#type-support) +- [Cache System](#cache-system) +- [Adding New Operations](#adding-new-operations) +- [Performance Considerations](#performance-considerations) +- [Debugging IL Generation](#debugging-il-generation) + +--- + +## Overview + +### Why IL Generation? + +You might wonder why NumSharp goes through the complexity of generating IL at runtime rather than using straightforward C# loops. The answer lies in the dramatic performance gains this approach enables. + +When you call an operation like `np.add(a, b)`, NumSharp doesn't simply iterate through elements with generic code. Instead, it generates specialized machine code tailored to your exact types and array layouts. This eliminates the overhead that would otherwise kill performance in a numerical computing library. + +NumSharp generates optimized machine code at runtime rather than relying on interpreted loops or generic abstractions. This provides: + +1. **Type Specialization** - Eliminates boxing/unboxing and virtual dispatch +2. **SIMD Vectorization** - Leverages Vector128/Vector256/Vector512 intrinsics +3. **Loop Fusion** - Combines operations to reduce memory traffic +4. **Stride Optimization** - Generates path-specific code for contiguous vs strided arrays + +### Performance Impact + +To give you a sense of the gains, here's what you can expect when IL kernels kick in compared to naive scalar implementations: + +| Scenario | Speedup vs Naive | +|----------|------------------| +| Contiguous SIMD (float/double) | 8-16x | +| Contiguous SIMD (int32/int64) | 4-8x | +| Strided arrays | 2-4x | +| Type promotion (int32 + float64) | 3-6x | + +These aren't theoretical numbersβ€”they reflect real-world benchmarks on modern CPUs with AVX2 support. If you're processing millions of elements, you'll see the difference immediately. + +--- + +## Architecture + +Understanding the architecture will help you navigate the codebase and know where to look when debugging or extending the system. + +### Core Components + +The `ILKernelGenerator` is a static partial class split across 28 files. Each file owns a specific category of operations, making it easier for you to find and modify the code you need. Here's the overall structure: + +``` +ILKernelGenerator (static partial class) +β”œβ”€β”€ Core Infrastructure (.cs) +β”‚ β”œβ”€β”€ Enabled flag, VectorBits detection +β”‚ β”œβ”€β”€ Type mapping (NPTypeCode ↔ CLR Type ↔ Vector type) +β”‚ └── Shared IL emission primitives +β”‚ +β”œβ”€β”€ Operation Partials +β”‚ β”œβ”€β”€ Binary operations (.Binary.cs, .MixedType.cs) +β”‚ β”œβ”€β”€ Unary operations (.Unary.*.cs) +β”‚ β”œβ”€β”€ Comparisons (.Comparison.cs) +β”‚ β”œβ”€β”€ Reductions (.Reduction.*.cs) +β”‚ β”œβ”€β”€ Scans (.Scan.cs) +β”‚ β”œβ”€β”€ Shifts (.Shift.cs) +β”‚ β”œβ”€β”€ MatMul (.MatMul.cs) +β”‚ └── Masking (.Masking.*.cs) +β”‚ +└── Supporting Classes + β”œβ”€β”€ StrideDetector - Execution path classification + β”œβ”€β”€ TypeRules - Type size, SIMD capability checks + β”œβ”€β”€ SimdThresholds - Minimum sizes for SIMD benefit + β”œβ”€β”€ SimdMatMul - Cache-blocked matrix multiplication + └── SimdReductionOptimized - Unrolled reduction kernels +``` + +### Flow: Request to Execution + +When you perform an operation like `a + b` on two NDArrays, here's what happens under the hood. Understanding this flow will help you debug issues and trace where performance bottlenecks might occur: + +``` +1. Caller (DefaultEngine, np.*, NDArray operator) + ↓ +2. ILKernelGenerator.Get*Kernel() or TryGet*Kernel() + ↓ +3. Cache lookup by operation key + ↓ (cache miss) +4. IL generation via DynamicMethod + ↓ +5. JIT compilation to native code + ↓ +6. Delegate cached and returned + ↓ +7. Caller invokes delegate with array pointers +``` + +The first time you execute a particular operation (say, adding two `float` arrays), there's a one-time cost to generate and JIT-compile the kernel. All subsequent calls with the same type and operation hit the cache, so you get the optimized delegate immediately. This is why the second iteration of your code often runs noticeably faster than the first. + +--- + +## File Organization + +When you need to modify or debug the IL generation code, knowing where to look is half the battle.

Not all arrays are created equalβ€”a contiguous array can use blazing-fast SIMD loops, while a transposed or sliced array may need coordinate-based iteration. + +### StrideDetector Classification + +Before executing any operation, NumSharp analyzes your arrays' memory layout using `StrideDetector.Classify()`. This determines which code path will be most efficient for your specific situation: + +```csharp +public enum ExecutionPath +{ + SimdFull, // Both operands contiguous - flat SIMD loop + SimdScalarRight, // RHS is scalar (all strides = 0) + SimdScalarLeft, // LHS is scalar (all strides = 0) + SimdChunk, // Inner dimension contiguous - chunked SIMD + General // Arbitrary strides - coordinate iteration +} +``` + +### Path Selection Logic + +Understanding this priority order helps you predict which path your code will take. If you're seeing slower-than-expected performance, check whether your arrays are hitting the General path when you expected SimdFull: + +```csharp +// Priority order (first match wins): +1. Both contiguous β†’ SimdFull (fastest) +2. RHS all strides = 0 β†’ SimdScalarRight (broadcast) +3. LHS all strides = 0 β†’ SimdScalarLeft (broadcast) +4. Inner stride = 1 or 0 for both β†’ SimdChunk +5. Otherwise β†’ General (coordinate-based) +``` + +**Tip:** If you need maximum performance, ensure your arrays are contiguous. You can check this with `ndarray.IsContiguous` or force contiguity with `np.ascontiguousarray()`. + +### Path-Specific Code Generation + +**SimdFull Path:** +``` +for i = 0 to count step vectorCount: + result[i:i+vc] = op(lhs[i:i+vc], rhs[i:i+vc]) // SIMD +for i = vectorEnd to count: + result[i] = op(lhs[i], rhs[i]) // scalar tail +``` + +**SimdScalarRight Path:** +``` +rhsVec = Vector256.Create(rhs[0]) // broadcast scalar +for i = 0 to count step vectorCount: + result[i:i+vc] = op(lhs[i:i+vc], rhsVec) +``` + +**General Path:** +``` +for linearIdx = 0 to totalSize: + coords = IndexToCoordinates(linearIdx, shape) + lhsOffset = dot(coords, lhsStrides) + rhsOffset = dot(coords, rhsStrides) + result[linearIdx] = op(lhs[lhsOffset], rhs[rhsOffset]) +``` + +--- + +## SIMD Optimization Techniques + +This section covers the optimization techniques used throughout the IL kernel system. If you're implementing a new operation or trying to squeeze out more performance, these patterns are your toolkit. + +### 1. Loop Unrolling (4x) + +You might think that processing one vector at a time is efficient enough, but modern CPUs can execute multiple independent instructions simultaneously. By unrolling the loop 4x, we give the CPU more work to parallelize: + +Processing 4 vectors per iteration reduces loop overhead and enables instruction-level parallelism: + +```csharp +// 4x unrolled SIMD loop +for (; i <= unrollEnd; i += vectorCount * 4) +{ + var v0 = Vector256.Load(data + i); + var v1 = Vector256.Load(data + i + vectorCount); + var v2 = Vector256.Load(data + i + vectorCount * 2); + var v3 = Vector256.Load(data + i + vectorCount * 3); + + acc0 += v0; // Independent - can execute in parallel + acc1 += v1; + acc2 += v2; + acc3 += v3; +} + +// Remainder loop (0-3 vectors) +for (; i <= vectorEnd; i += vectorCount) + acc0 += Vector256.Load(data + i); + +// Scalar tail +for (; i < size; i++) + result += data[i]; +``` + +### 2. Tree Reduction + +When you have 4 accumulator vectors and need to combine them into a single result, the naive approach creates a serial dependency chain where each addition must wait for the previous one. Tree reduction solves this by allowing parallel execution: + +```csharp +// Instead of: result = acc0 + acc1 + acc2 + acc3 (serial - each add waits for previous) +// Use tree pattern: +var sum01 = acc0 + acc1; // Can execute in parallel +var sum23 = acc2 + acc3; // Can execute in parallel +var sumAll = sum01 + sum23; +double result = Vector256.Sum(sumAll); +``` + +This might seem like a minor detail, but it can make a significant difference on modern out-of-order CPUs. + +### 3. Multiple Accumulator Vectors + +Using independent accumulators maximizes instruction-level parallelism (ILP): + +```csharp +// 4 independent accumulators - no dependency between updates +var acc0 = Vector256.Zero; +var acc1 = Vector256.Zero; +var acc2 = Vector256.Zero; +var acc3 = Vector256.Zero; +``` + +### 4. FMA (Fused Multiply-Add) + +If you're running on a CPU with FMA support (most Intel Haswell and newer, AMD Piledriver and newer), you get a significant boost. FMA performs `a * b + c` in a single instruction with only one rounding step, which is both faster and more accurate: + +```csharp +if (Fma.IsSupported) + c = Fma.MultiplyAdd(a, b, c); // c = a * b + c in one instruction +else + c = Vector256.Add(c, Vector256.Multiply(a, b)); +``` + +The IL kernel system automatically detects FMA availability at runtime and uses it when possible. You don't need to do anything specialβ€”just make sure you're running on capable hardware. + +### 5. Cache Blocking (MatMul) + +Matrix multiplication is where cache blocking becomes critical. Without it, you'd constantly fetch data from main memory, destroying performance. The GEBP (General Block Panel) algorithm ensures that your working set fits in cache: + +```csharp +// Block sizes tuned for L1=32KB, L2=256KB +const int MC = 64; // A panel rows +const int KC = 256; // K depth +const int MR = 8; // Micro-kernel rows +const int NR = 16; // Micro-kernel cols (2 vectors) + +// Panel packing: A[kc][MR], B[kc][NR] for sequential access +``` + +These constants were tuned empirically for typical modern CPUs. If you're targeting specialized hardware, you might benefit from different values. + +### 6. Early Exit (Boolean Reductions) + +For `np.all()` and `np.any()`, you don't always need to scan the entire array. If you're checking whether all elements are true and you find a false, you can stop immediately. The IL kernels exploit this with SIMD-accelerated early exit: + +```csharp +// All: exit when first zero found +for (; i <= vectorEnd; i += vectorCount) +{ + var vec = Vector256.Load(data + i); + if (Vector256.EqualsAny(vec, zero)) + return false; // Early exit! +} + +// Any: exit when first non-zero found +for (; i <= vectorEnd; i += vectorCount) +{ + var vec = Vector256.Load(data + i); + if (!Vector256.EqualsAll(vec, zero)) + return true; // Early exit! +} +``` + +--- + +## Operation Coverage + +### Binary Operations + +| Operation | SIMD | Scalar | Types | +|-----------|------|--------|-------| +| Add | Vector256 op_Addition | OpCodes.Add | All numeric | +| Subtract | Vector256 op_Subtraction | OpCodes.Sub | All numeric | +| Multiply | Vector256 op_Multiply | OpCodes.Mul | All numeric | +| Divide | Vector256 op_Division | OpCodes.Div/Div_Un | All numeric | +| Power | -

Changes by category: Loop counters and index variables: - Change `int vectorCount` to `long vectorCount` in all IL emission methods - Replace `Ldc_I4, vectorCount; Conv_I8` with direct `Ldc_I8, vectorCount` - Use `Ldc_I8, 1L` for loop increments on long locals Pointer arithmetic pattern change: - Old: `Conv_I; Ldc_I4, elementSize; Mul; Add` - New: `Ldc_I8, (long)elementSize; Mul; Conv_I; Add` This keeps all arithmetic as int64 until the final pointer operation, which is cleaner and more consistent.

Using unmanaged memory instead of managed arrays where possible 2. Adding overflow checks with clear error messages for platform limits 3. Adding stride checks to avoid silent truncation in SIMD paths 4.

charset=UTF-8 Content-Transfer-Encoding: 8bit Convert UnmanagedSpan and ReadOnlyUnmanagedSpan from int to long: Core changes in both types: - _length field: int β†’ long - Length property: int β†’ long - Indexer: this[int] β†’ this[long] - Slice methods: (int start) β†’ (long start), (int, int) β†’ (long, long) - Pointer constructor: (void*, int) β†’ (void*, long) - Internal constructor: (ref T, int) β†’ (ref T, long) - Enumerator._index: int β†’ long Bounds checking updated: - Changed (uint)x casts to (ulong)x for proper 64-bit comparisons - Removed /* force zero-extension */ casts that are no longer needed Array constructors retain int parameters since .NET arrays use int indices. This enables UnmanagedSpan to represent >2 billion element arrays, which is the core requirement for NumSharp's long indexing support. --- docs/plans/gh-issue-npy-npz-rewrite.md | 144 +

+1,144 @@ +# [Rewrite] np.save/load - NPY/NPZ Format (NEP-01) + +## Overview + +NumSharp's implementation of `.npy` and `.npz` file I/O needs a complete rewrite. The current code was written as a quick solution years ago and has accumulated significant technical debt. It diverges from NumPy's behavior in ways that break interoperability, throws exceptions on valid files that NumPy handles gracefully, and exposes an API that doesn't match NumPy's signatures. This issue proposes bringing the implementation into full compliance with NEP-01 (the NumPy Enhancement Proposal that defines the binary format) and achieving API parity with NumPy 2.x. + +## The Problem + +### We Only Support a Fraction of the Format + +The NPY format has evolved through three versions since its introduction in NumPy 1.0.5. Version 1.0 uses a 2-byte header length field, limiting headers to 65KB - plenty for simple arrays but insufficient for structured arrays with many fields. Version 2.0, introduced in NumPy 1.9, extended this to a 4-byte field supporting headers up to 4GB. Version 3.0, added in NumPy 1.17, switched the header encoding from Latin-1 to UTF-8 to support Unicode field names in structured dtypes. + +NumSharp currently only recognizes version 1.0 and throws `NotSupportedException` when encountering version 2.0 or 3.0 files. This means any `.npy` file saved by modern NumPy with a large structured dtype or Unicode field names simply cannot be loaded. Users hitting this wall have no workaround other than re-saving their data in NumPy with simpler dtypes. + +### Header Alignment is Wrong + +One of the cleverest aspects of the NPY format is that the header is padded so the data section begins at a 64-byte aligned offset. This alignment enables memory-mapped access to the array data without copying - the operating system can map the file directly into virtual memory and the CPU can access the data with aligned SIMD instructions. + +NumSharp's implementation uses 16-byte alignment instead of 64. Files written by NumSharp technically conform to the format specification (alignment is not strictly required), but they lose the performance benefits of memory mapping. More importantly, this signals a fundamental misunderstanding of the format that likely indicates other subtle bugs. + +### We Reject Valid Data Layouts + +NumPy arrays can be stored in either C-order (row-major) or Fortran-order (column-major) layout. The format captures this in the `fortran_order` header field. When NumPy encounters a Fortran-order file, it reads the data, reshapes with reversed dimensions, then transposes to produce the correct array. + +NumSharp throws an exception when `fortran_order` is `True`. This is particularly frustrating because Fortran-order arrays are common in scientific computing - they're the native layout for MATLAB, R, and many numerical libraries. A user trying to load data exported from these tools will simply get an error with no path forward. + +The same issue applies to byte order. NumPy files can contain big-endian data (indicated by `>` in the dtype descriptor). NumPy handles this transparently by byte-swapping on read when the host system uses a different byte order. NumSharp throws an exception. While big-endian systems are rare today, big-endian files still exist - especially in legacy scientific datasets and network protocols. + +### The API Doesn't Match NumPy + +When users learn NumPy, they learn to call `np.save()`, `np.load()`, `np.savez()`, and `np.savez_compressed()`. These function signatures have specific parameters with specific defaults that users come to expect. + +NumSharp's API diverges in several ways. The methods are named `Save_Npz` and `Load_Npz` instead of `savez` - mixing PascalCase with underscores in a way that matches neither .NET conventions nor NumPy conventions. The `load` function is missing critical parameters like `allow_pickle` (which controls whether object arrays can be loaded), `mmap_mode` (for memory-mapped access), and `max_header_size` (a security feature that limits header parsing to prevent denial-of-service attacks from malicious files). + +The `Load_Npz` method requires a generic type parameter with a complex constraint (`where T : class, ICloneable, IList, ICollection, IEnumerable, IStructuralComparable, IStructuralEquatable`). This constraint exists because the implementation returns .NET arrays rather than NDArrays, but it creates an awkward API that doesn't exist in NumPy. Users shouldn't need to specify type parameters to load a file - the type information is in the file itself. + +### NPZ Handling Has Subtle Bugs + +The `.npz` format is simply a ZIP archive containing multiple `.npy` files. NumPy's `NpzFile` class provides lazy loading - arrays aren't actually read from disk until accessed. It also provides a convenient interface where both `npz['arr_0']` and `npz['arr_0.npy']` work as keys, with the `.files` property returning the stripped names. + +NumSharp's `NpzDictionary` class doesn't strip the `.npy` extension, so code written for NumPy that accesses arrays by their logical names will fail. The class also doesn't implement the context manager protocol properly for deterministic cleanup, potentially leaking file handles. + +### Security Features Are Missing + +NumPy added the `max_header_size` parameter after discovering that `ast.literal_eval()` (used to parse the header dictionary) can be slow or even crash on extremely large inputs. A malicious actor could craft a `.npy` file with a header designed to cause denial of service. The default limit of 10,000 bytes is sufficient for any legitimate array while protecting against attacks. + +NumPy also changed `allow_pickle` to default to `False` in version 1.16.3 after security researchers demonstrated that pickle deserialization could execute arbitrary code. Object arrays in `.npy` files are serialized using pickle, so loading an untrusted file with `allow_pickle=True` is equivalent to running untrusted code. + +NumSharp has neither protection. There's no header size limit, and there's no pickle support at all (which means object arrays simply can't be loaded, but also means there's no parameter to control this behavior). + +### Dtype Coverage is Incomplete + +The dtype descriptor in an NPY header maps directly to NumPy's dtype system. NumSharp's parser handles the common cases but has gaps and bugs. + +The unsigned byte type `|u1` is mapped to signed byte, which is simply wrong. Complex number types (`` with an `NpzFile` class that matches NumPy's interface. This class should: + +- Provide lazy loading with internal caching (arrays loaded on first access, then cached) +- Accept both `"arr_0"` and `"arr_0.npy"` as valid keys +- Expose a `files` property with stripped names +- Implement `IDisposable` properly for the underlying ZIP archive +- Support the `f` attribute for dot-notation access (`npz.f.weights` instead of `npz["weights"]`) + +The `savez` and `savez_compressed` functions should accept both positional arrays (named `arr_0`, `arr_1`, etc.) and keyword arguments. They should always enable Zip64 extensions to support archives larger than 4GB. + +### Match the NumPy API + +The public API should match NumPy's signatures: + +```python +np.save(file, arr, allow_pickle=True) +np.load(file, mmap_mode=None, allow_pickle=False, fix_imports=True, + encoding='ASCII', *, max_header_size=10000) +np.savez(file, *args, allow_pickle=True, **kwds) +np.savez_compressed(file, *args, allow_pickle=True, **kwds) +``` + +The `allow_pickle` parameter should be implemented even though we don't support pickle - it should raise a clear error when `allow_pickle=False` and an object array is encountered, matching NumPy's behavior. + +The `mmap_mode` parameter enables memory-mapped access. While full implementation is complex, at minimum we should accept the parameter and either implement basic read-only mapping or raise `NotImplementedException` with a clear message. + +### Add Security Protections + +Implement the `max_header_size` check. Before parsing the header with any string operations, verify its length is within the limit. If `allow_pickle=True`, the limit can be bypassed (the user has already indicated they trust the file). + +Validate the header dictionary strictly: exactly three keys (`descr`, `fortran_order`, `shape`), `shape` must be a tuple of non-negative integers, `fortran_order` must be a boolean, `descr` must produce a valid dtype. + +### Improve Error Messages + +Replace generic exceptions with descriptive messages that help users understand what went wrong. NumPy's error messages are a good template: + +- `"the magic string is not correct; expected b'\\x93NUMPY', got {actual!r}"` +- `"we only support format version (1,0), (2,0), and (3,0), not {version}"` +- `"Header does not contain the correct keys: {keys!r}"` +- `"Object arrays cannot be loaded when allow_pickle=False"` + +## Breaking Changes + +This rewrite will change the public API. The `Save_Npz` and `Load_Npz` methods will be deprecated in favor of `savez` and `load`. The `NpzDictionary` class will be replaced by `NpzFile`. Code that depends on these will need to be updated. + +The default value of `allow_pickle` on `load` will be `False` to match NumPy's security-conscious default. Code that loads object arrays will need to explicitly pass `allow_pickle=True`. + +Files written by the old implementation with 16-byte alignment will still be readable, but memory mapping performance characteristics may differ. + +## What We're Not Doing (Yet) + +Some features are out of scope for this rewrite: + +**Object arrays** require implementing Python's pickle protocol, which is a substantial undertaking with security implications. For now, we'll raise a clear error when object arrays are encountered. + +**Structured dtypes** (record arrays) are complex to map to .NET types. A future enhancement could support them via dynamically generated types or a generic record class. + +**datetime64 and timedelta64** need design decisions about how to map to .NET types (`DateTime`, `DateTimeOffset`, `TimeSpan`, or custom structs). + +**Memory-mapped write mode** is complex because it requires pre-allocating the file to the correct size and carefully managing the mapping lifetime. + +## References + +The authoritative source for the NPY format is NEP-01, available at https://numpy.org/neps/nep-0001-npy-format.html. The implementation lives in `numpy/lib/_format_impl.py` (low-level format handling) and `numpy/lib/_npyio_impl.py` (high-level `save`/`load` functions). + +I've prepared comprehensive documentation of the format in `docs/numpy/NUMPY_NPZ_SAVE_LOAD.md` based on reading the NumPy source code. This covers every constant, every function, every edge case, and every error message. It should serve as the specification for our implementation. diff --git a/docs/plans/il-int64.md b/docs/plans/il-int64.md new file mode 100644 index 000000000..782927c2c --- /dev/null +++ b/docs/plans/il-int64.md @@ -0,0 +1,942 @@ +# IL Kernel Generator: Int64 Migration Plan + +## Executive Summary + +The ILKernelGenerator system generates high-performance SIMD kernels at runtime using `System.Reflection.Emit`.

The core issue is that C# variables like `vectorCount`, `unrollStep`, and `offset` are declared as `int`, leading to `Ldc_I4` IL emissions that create type mismatches with `long` loop counters and array sizes. + +The fix is straightforward: +1. Declare these variables as `long` +2. Use `Ldc_I8` for all emissions +3. Replace `Ldc_I4_1` with `Ldc_I8, 1L` for increments + +This ensures type consistency throughout the generated IL and aligns with the project's int64 indexing goals. diff --git a/src/NumSharp.Core/Utilities/SpanSource/ReadOnlyUnmanagedSpan.cs b/src/NumSharp.Core/Utilities/SpanSource/ReadOnlyUnmanagedSpan.cs index 6711cb9d9..764f68565 100644 --- a/src/NumSharp.Core/Utilities/SpanSource/ReadOnlyUnmanagedSpan.cs +++ b/src/NumSharp.Core/Utilities/SpanSource/ReadOnlyUnmanagedSpan.cs @@ -31,7 +31,7 @@ public readonly ref struct ReadOnlyUnmanagedSpan /// A byref or a native ptr. internal readonly ref T _reference; /// The number of elements this ReadOnlyUnmanagedSpan contains. - private readonly int _length; + private readonly long _length; /// /// Creates a new read-only span over the entirety of the target array. @@ -102,7 +102,7 @@ public ReadOnlyUnmanagedSpan(T[]? array, int start, int length) [CLSCompliant(false)] [MethodImpl(MethodImplOptions.AggressiveInlining)] [RequiresUnsafe] - public unsafe ReadOnlyUnmanagedSpan(void* pointer, int length) + public unsafe ReadOnlyUnmanagedSpan(void* pointer, long length) { if (RuntimeHelpers.IsReferenceOrContainsReferences()) ThrowHelper.ThrowArgument_TypeContainsReferences(typeof(T)); @@ -124,7 +124,7 @@ public ReadOnlyUnmanagedSpan(ref readonly T reference) // Constructor for internal use only.

If the garbage collector happens to move the + // sequences afterwards and the sequences overlapped before, they will + // still overlap after the move and their distance hasn't changed. If + // the sequences did not overlap, the distance can change but the + // sequences still won't overlap. + // + // The second problem is solved by making all addresses relative to the + // start of the first sequence and performing all operations in + // unsigned integer arithmetic modulo 2^32. + // + // Example + // ------- + // + // Let's say there are two sequences, x and y. Let + // + // ref T xRef = MemoryMarshal.GetReference(x) + // uint xLength = x.Length * sizeof(T) + // ref T yRef = MemoryMarshal.GetReference(y) + // uint yLength = y.Length * sizeof(T) + // + // Visually, the two sequences are located somewhere in the 32-bit + // address space as follows: + // + // [----------------------------------------------) normal address space + // 0 2^32 + // [------------------) first sequence + // xRef xRef + xLength + // [--------------------------) . second sequence + // yRef . yRef + yLength + // : . . . + // : . . . + // . . . + // . . . + // . . . + // [----------------------------------------------) relative address space + // 0 . . 2^32 + // [------------------) : first sequence + // x1 . x2 : + // -------------) [------------- second sequence + // y2 y1 + // + // The idea is to make all addresses relative to xRef: Let x1 be the + // start address of x in this relative address space, x2 the end + // address of x, y1 the start address of y, and y2 the end address of + // y: + // + // nuint x1 = 0 + // nuint x2 = xLength + // nuint y1 = (nuint)Unsafe.ByteOffset(xRef, yRef) + // nuint y2 = y1 + yLength + // + // xRef relative to xRef is 0. + // + // x2 is simply x1 + xLength. This cannot overflow. + // + // yRef relative to xRef is (yRef - xRef). If (yRef - xRef) is + // negative, casting it to an unsigned 32-bit integer turns it into + // (yRef - xRef + 2^32). So, in the example above, y1 moves to the right + // of x2. + // + // y2 is simply y1 + yLength. Note that this can overflow, as in the + // example above, which must be avoided. + // + // The two sequences do *not* overlap if y is entirely in the space + // right of x in the relative address space.

If the garbage collector happens to move the - // sequences afterwards and the sequences overlapped before, they will - // still overlap after the move and their distance hasn't changed. If - // the sequences did not overlap, the distance can change but the - // sequences still won't overlap. - // - // The second problem is solved by making all addresses relative to the - // start of the first sequence and performing all operations in - // unsigned integer arithmetic modulo 2^32. - // - // Example - // ------- - // - // Let's say there are two sequences, x and y. Let - // - // ref T xRef = MemoryMarshal.GetReference(x) - // uint xLength = x.Length * sizeof(T) - // ref T yRef = MemoryMarshal.GetReference(y) - // uint yLength = y.Length * sizeof(T) - // - // Visually, the two sequences are located somewhere in the 32-bit - // address space as follows: - // - // [----------------------------------------------) normal address space - // 0 2^32 - // [------------------) first sequence - // xRef xRef + xLength - // [--------------------------) . second sequence - // yRef . yRef + yLength - // : . . . - // : . . . - // . . . - // . . . - // . . . - // [----------------------------------------------) relative address space - // 0 . . 2^32 - // [------------------) : first sequence - // x1 . x2 : - // -------------) [------------- second sequence - // y2 y1 - // - // The idea is to make all addresses relative to xRef: Let x1 be the - // start address of x in this relative address space, x2 the end - // address of x, y1 the start address of y, and y2 the end address of - // y: - // - // nuint x1 = 0 - // nuint x2 = xLength - // nuint y1 = (nuint)Unsafe.ByteOffset(xRef, yRef) - // nuint y2 = y1 + yLength - // - // xRef relative to xRef is 0. - // - // x2 is simply x1 + xLength. This cannot overflow. - // - // yRef relative to xRef is (yRef - xRef). If (yRef - xRef) is - // negative, casting it to an unsigned 32-bit integer turns it into - // (yRef - xRef + 2^32). So, in the example above, y1 moves to the right - // of x2. - // - // y2 is simply y1 + yLength. Note that this can overflow, as in the - // example above, which must be avoided. - // - // The two sequences do *not* overlap if y is entirely in the space - // right of x in the relative address space. (It can't be left of it!) - // - // (y1 >= x2) && (y2 <= 2^32) - // - // Inversely, they do overlap if - // - // (y1 < x2) || (y2 > 2^32) - // - // After substituting x2 and y2 with their respective definition: - // - // == (y1 < xLength) || (y1 + yLength > 2^32) - // - // Since yLength can't be greater than the size of the address space, - // the overflow can be avoided as follows: - // - // == (y1 < xLength) || (y1 > 2^32 - yLength) - // - // However, 2^32 cannot be stored in an unsigned 32-bit integer, so one - // more change is needed to keep doing everything with unsigned 32-bit - // integers: - // - // == (y1 < xLength) || (y1 > -yLength) - // - // Due to modulo arithmetic, this gives exactly same result *except* if - // yLength is zero, since 2^32 - 0 is 0 and not 2^32.
