+<h3>Deploying and Supporting Julia at NERSC</h3>
+Speaker: Johannes Blaschke<br>
+National Energy Research Scientific Computing Center<br>
+Application Performance Specialist<br><br>
+
+Abstract:
+<p>
+Julia has been supported as a first-class language on NERSC's systems for over 10 years [1]. In this talk we will discuss how Julia has been deployed at scale, the technical issues encountered and how they were eventually overcome. We will also explore the challenges faced with developing intuitive and portable distributed HPC applications that are capable of targeting modern GPU architectures, and NERSC's vision for supporting modern interdisciplinary and multi-facility workflows.

+Bio:
+<p>
+Johannes Blaschke is a HPC workflow performance expert leading the NERSC Science Acceleration Program (NESAP). His research interests include urgent and interactive HPC; and programming environments and models for cross-facility workflows. Johannes supports Julia on NERSC's systems, including one of the first examples of integrating MPI.jl and Distributed.jl with the HPE's Slingshot network technology. Johannes is a zealous advocate for Julia as an HPC programming language, and a contributor and organizer of Julia tutorials and BoFs at SC, JuliaCon and within the DoE.
