Center Announcements

Andes Is Available; Rhea Will Be Decommissioned
As a reminder, Andes, our new data analysis cluster, is now available for use. Andes has 704 nodes with 2 AMD EPYC 7302 16-core processors and 256 GB of memory along with the 9 nodes from the older rhea-gpu partition. Andes can be accessed at andes.olcf.ornl.gov and a user guide is available at https://docs.olcf.ornl.gov/systems/andes_user_guide.html. Our previous data analysis cluster, Rhea, has been decommissioned and is no longer available.

2021 GPU Hackathons
The 2021 NVIDIA GPU Hackathon Season is now open. You can find all the GPU hackathon dates and register to participate at https://www.gpuhackathons.org/events. Events that will be supported by OLCF computing resources and staff are marked with the OLCF logo. The next OLCF supported hackathon will be held virtually by ANL on April 20 and April 27-29, 2021.

Upcoming Scheduled Outages

Work will be performed on Marble from 8:00 AM until 4:00 PM on Tuesday, January 26. Workflows should migrate between servers during this maintenance, so no user impact is anticipated.
