Center Announcements

Andes Available December 8
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.

All Rhea projects will be given access to Andes on December 8. Andes mounts the same user filesystems as Rhea, so no data movement is necessary. Andes can be accessed via ssh to A user guide is available at We encourage you to begin using Andes immediately. If you have any questions, please contact the User Assistance Center at
