We have added two login nodes to Glenn (opt-login05 and opt-login06), which are quad-socket computers with 64 GB of RAM. These were previously used as large memory nodes on Glenn, and will provide greater resources to the shared environment on the login nodes. The original login nodes are still in service, but users are no longer directed to them via the round-robin service at glenn.osc.edu, and they will eventually be turned off. If you are directly connecting to one of these nodes, please migrate to the new login nodes.
Update Tue Feb 10th 11:30am -- This issue is resolved.
There is a bug in the changes we made to a part of our batch software during the downtime. The bug is affecting some users when they submit jobs to our system.
