OLCF Ticket System Updates
OLCF will transition to a new ticket system (Jira) this week. We do not anticipate this change to impact users but we wanted to let you know since email responses to new tickets will have a different look and may show up as coming from a new email address (jira-consult@ccs.ornl.gov). You should continue to submit new issues to help@olcf.ornl.gov. Additionally, you can respond to any issue (either existing ones or newly submitted ones) by simply replying to one of the emails you’ve received from us related to the issue.

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.

With the availability of Andes, our previous data analysis system, Rhea, will be decommissioned on January 15, 2021. Although Rhea remains available until then, we encourage you to move your work to Andes immediately.

Upcoming Scheduled Outages

HPSS will be unavailable from 8:00 AM until noon on Tuesday, January 12.

Summit, Andes, the Alpine filesystem, and the Data Transfer Nodes will be unavailable beginning at 8:00 AM on Tuesday, January 19. Andes, Alpine, and the DTNs will return to service at 4:00 PM while Summit will remain unavailable until 8:00 PM.
