The Partitions and resource limits#
To request access to partitions on demand such as the bigmem node or the gpu nodes, please submit your request on the community support platform: community support website specifying your login and project name.
⚠️ The values below can change. To check the current situation:
scontrol show partition
sacctmgr list qos format=Name,Priority,MaxTRESPU%20
| Partitions | Time out | Max resources / user | Purpose |
|---|---|---|---|
fast |
<= 24 hours | cpu=300, mem=1500GB | Default - Regular jobs |
long |
<= 30 days | cpu=300, mem=1500GB | Long jobs |
bigmem |
<= 60 days | mem=4000GB | On demand - For jobs requiring a lot of RAM |
gpu |
<= 3 days | cpu=300, mem=1500GB | On demand - Access GPU cards |
