The changes in favor of Petra4-computing tasks announced Aug. 17th have been reverted, and new nodes and partitions have been added accordingly:
- The maxwell partition has been restored with all nodes and a maximum job runtime of 7 days.
- The petra4 partition has been increased by 40 new AMD EPYC-7402 nodes
- A new short partition has been created.
- The short partition also contains the 40 new AMD EPYC-7402 nodes
- The maximum job runtime is 4 hours
- jobs in the petra4 partition are prioritized. Jobs in the short partition might be delayed but will never be terminated (preempted).
A short overview of the relevant changes:
Partition | # of nodes | Nodes/Job | Max # of Jobs | Default Time | Maximum Time | Allowed Groups |
|---|---|---|---|---|---|---|
| maxwell | 58 | 1-6 | 8 | 1:00:00 | 7-00:00:00 | maxwell-users |
| petra4 | 66 | no limit | no limit | 1:00:00 | 14-00:00:00 | max-petra4-sim-users |
| short | 40 | 1-4 | 8 | 1:00:00 | 4:00:00 | maxwell-users |
