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).

Some useful commands to get more information about  the current setup:

/usr/local/bin/max-limits -a                       # show partitions and the limits applying 
/usr/local/bin/max-limits                          # show only partitions allowed
/usr/local/bin/my-partitions                       # list partitions indicating which ones can be used and which ones not

/usr/bin/sinfo                                     # show available nodes and partitions
/usr/bin/sinfo -p short -o '%20n %20f %10t %c %m'  # show nodes in the short partition, with state, features, cores...

/software/tools/bin/savail -p maxgpu               # show detailed information about available nodes taking into account preemptable jobs
