Center Announcements

User Assistance Center Schedule
The OLCF User Assistance Center will be closed on Friday, December 31 due to an ORNL-observed holiday.

The normal user assistance schedule will resume on Monday, January 3. The ORNL Computer Operations staff will remain available for limited troubleshooting 24 hours a day.

Meetings & Workshops

Perlmutter Training (Jan 5-7)
NERSC will host Perlmutter training on Jan 5 -7 provided jointly by HPE and NERSC staff. This is a continuation and extension of the June 2021 Perlmutter Introduction training, now focused more on using Perlmutter with hands-on exercises. ALCF and OLCF users are invited to this training, and NERSC training accounts will be provided based on availability and time of registration. Registration is available via this link.

HPC Best Practices Webinar (Jan 12)
The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) run a webinar series on Best Practices for HPC Software Developers. The January webinar will be presented by Philip Roth of ORNL and is titled Wrong Way: Lessons Learned and Possibilities for Using the “Wrong” Programming Approach on Leadership Computing Facility Systems. The webinar will take place on Wednesday, January 12, 2022 at 1:00 pm ET. The webinar is free and open to the public, but registration is required and is available at

NVIDIA HPC SDK Training (Jan 12-13)
On January 12-13, NVIDIA will present a 2-day seminar for NERSC, ALCF, and OLCF users about the various GPU programming models supported by NVIDIA’s HPC SDK compilers, including Standard Language Acceleration and Libraries, OpenACC, OpenMP offload, and CUDA. The basic GPU architecture and HPC SW developer considerations and the profiling tools will also be presented. Attendees will have the opportunity to do hands-on and homework exercises on Perlmutter Phase 1 GPUs (NERSC and ALCF users) and on Summit (OLCF users). The agenda and registration form are available via this link.

Vampir/Score-P Training (Jan 19-20)
OLCF will host Vampir and Score-P training on January 19-20 from 9:00-11:30 AM EST each day. Vampir is an established performance tool for visualizing and analyzing the behavior of highly parallel HPC applications. It is supported by the Score-P tool, which can be used to fully record the runtime behavior of HPC applications. The first day will feature lessons and hands-on demos using these tools. The second day will give users an opportunity to bring their own codes and instrument them for performance analysis with help from Score-P and Vampir developers.
