Center Announcements

User Assistance Center Schedule
The OLCF User Assistance Center will be closed on Thursday, November 26 and Friday, November 27 due to ORNL-observed holidays. The normal user assistance schedule will resume on Monday, November 30.

NOTE: The ORNL Computer Operations staff will remain available for limited troubleshooting 24 hours a day.

New Data Analysis Cluster: Andes
As earlier announced, we will soon replace our data analysis cluster Rhea with a new system named Andes. Andes will contain 704 compute nodes, each with two 16-core AMD EPYC processors and 256 GB of memory. Additionally, the GPU/High-Memory nodes currently in Rhea’s ‘rhea-gpu’ partition will be moved over to Andes.

Watch future Weekly Updates for the availability timeline. In the meantime, we suggest users begin reviewing the Andes User Guide. If you have any questions or if you would like to be an early user of the Andes system, please contact the User Assistance Center at

OpenMP Off Load Training December 8 and 10
NVIDIA will present a 2-part training series for NERSC and OLCF users about using OpenMP target offload with NVIDIA’s HPC SDK compilers. The training will introduce OpenMP target offload, the NVIDIA compilers, and best practices for achieving high performance with OpenMP target offload on NVIDIA GPUs. Access to Cori GPU nodes will be provided.

The event page for the workshop contains the schedule and a registration link. The registration form is also available via this link. There is no registration fee.
