CENTER ANNOUNCEMENTS

OPENMPI UPGRADE ON RHEA (FEB 18)
Rhea’s default OpenMPI will be upgraded to version 3.1.4 on February 18. Due to changes that will be made to underlying system libraries during the outage, all codes built against OpenMPI must be rebuilt once Rhea returns to service.

MEETINGS & WORKSHOPS

JSRUN TUTORIAL (FEB 18)
OLCF will hold a jsrun tutorial on Tuesday, February 18, 2020. This event is intended to teach new and existing OLCF users how to use the jsrun job launcher on Summit. We will begin with an introduction to jsrun – to bring new users up to speed – followed by more advanced usage (e.g., using Explicit Resource Files (ERF)). After the presentations, participants will be encouraged to work through example problems during a hands-on session.

Both in-person and remote participation will be supported during the tutorial, but only in-person participants will be given temporary training accounts on Summit (for those who do not already have access). The connection details will be sent out to remote participants the day before the event.

To register for on-site or remote attendance, please visit the event page. If you have any questions, please contact Tom Papatheodore.

NVIDIA PROFILING TOOLS – NSIGHT SYSTEMS (MAR 9)
On March 9, NVIDIA will present a webinar on how to use NVIDIA’s Nsight Systems – a statistical sampling profiler with tracing features – on Summit. Nsight Systems and Nsight Compute are NVIDIA’s next-generation profiling tools for understanding and optimizing the performance of CUDA, OpenACC, or OpenMP applications. NVIDIA recommends transitioning to these new tools since nvprof and Visual profiler will be deprecated in a future CUDA release. The presentation will be delivered remotely but there will be an in-person viewing of the webinar for participants with current ORNL badges. For more information or to register, please visit the event page.

NVIDIA PROFILING TOOLS – NSIGHT COMPUTE (MAR 10)
On March 10, NVIDIA will present a webinar on how to use NVIDIA’s Nsight Compute – a kernel-level analysis and performance metric tool – on Summit. Nsight Systems and Nsight Compute are NVIDIA’s next-generation profiling tools for understanding and optimizing the performance of CUDA, OpenACC, or OpenMP applications. NVIDIA recommends transitioning to these new tools since nvprof and Visual profiler will be deprecated in a future CUDA release. The presentation will be delivered remotely but there will be an in-person viewing of the webinar for participants with current ORNL badges.
