User Assistance Center Schedule
The OLCF User Assistance Center will be closed on Thursday, November 25 and Friday, November 26 due to ORNL-observed holidays. The normal user assistance schedule will resume on Monday, November 29. NOTE: The ORNL Computer Operations staff will remain available for limited troubleshooting 24 hours a day.
ALCC Call for Proposals
The DOE Office of Advanced Scientific Computing Research (ASCR) is now accepting application proposals for the 2022-23 allocation year of the ASCR Leadership Computing Challenge (ALCC) program. The program provides access to computational resources at ASCR’s three supercomputing facilities (OLCF, ALCF, and NERSC).
The proposal process consists of two steps, with a pre-proposal due on December 17, 2021 and the full proposal due on February 22, 2022. The allocation period for successful proposals will run from July 1, 2022-June 30, 2023.

Software Changes on Andes
Andes will be unavailable on Tuesday, November 30 for a minor OS upgrade. In addition to the OS change, new versions of the Mellanox InfiniBand Driver, NVIDIA Driver, and Slurm will be installed. While recompiling is not required, it is recommended. A summary of the changes is available at https://docs.olcf.ornl.gov/software/software-news.html.
Meetings & Workshops
OLCF User Conference Call (Dec 8)
There will not be an OLCF User Conference Call in November. The final call for the year will be held at noon (Eastern Time) on Wednesday, December 8. The December call will include a discussion on analysis tools at OLCF led by Benjamin Hernandez. For more information on that call, see https://www.olcf.ornl.gov/calendar/userconcall-dec2021/.
Vampir/Score-P Training (Jan 19-20)
OLCF will host a Vampir and Score-P training on January 19-20 from 9:00 am-11:30 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.
For the detailed agenda and registration please see https://www.olcf.ornl.gov/calendar/vampir-score-p-training/.
Upcoming Scheduled Outages
- Andes will be unavailable from 7:00 AM until 11:59 PM on Tuesday, November 30.
