In O2 we minimized the number of available partitions (or queues) to simplify the job submission process.
You can use the flow chart below to find out which partition is best for the type of jobs you plan to run.
Note 1: all partitions can currently be used to request interactive sessions; the interactive partition has a dedicated set of nodes and higher priority.
Note 2: all partitions can run single or multi-core jobs (O2 does not have an mcore queue). For more information about parallel jobs in O2 read our dedicated wiki page
Details about the available partitions are reported in the table below
Partition | Job Type | Priority | Max cores per job | Max runtime limit | Min runtime limit | Notes |
|---|---|---|---|---|---|---|
| interactive | interactive | 14 | 20 | 12 hours | n/a | 2 job limit, 20 core/job limit, 250GiB / job memory limit |
| short | batch & interactive | 12 | 20 | 12 hours | n/a | 20 core/job limit, 250GiB / job memory limit |
