The compute nodes of the CPU cluster of system Lise are organised via the following slurm Slurm partitions.
Partition name | Node numbercount | CPU | Main memory (GB) | Max. nodes per job | Max. jobs per user (running/ queued)per user | Walltime Wall time limit (hh:mm:ss) | Remark |
|---|---|---|---|---|---|---|---|
| standard96cpu-clx | 1204688 | Cascade 9242 | 362 | 512 | 128 / 500 | 12:00:00 | default partition |
| standard96cpu-clx:test | 32 dedicated +128 on demand | 362 | 16 | 1 / 500 | 01:00:00 | test nodes with higher priority but lower walltimeless wall time | |
| large96 | 28 | 747 | 8 | 128 / 500 | 12:00:00 | fat memory nodes | |

If you do not request a partition, your job will be placed in the default partition, which is standard96.
The default partitions are partition is suitable for most calculations. The :test partitions are, as the name suggests, intended for shorter and smaller test runs. These have a higher priority and a few dedicated nodes, but are limited in time and number of nodesprovide only limited resources. Shared nodes are suitable for pre- and postprocessingpost-processing. A job running on a shared node is only accounted for its core fraction (cores of job / all cores per node). All non-shared nodes are exclusive to one job only at a time.
The available home/local-ssd/work/perm storages file systems are discussed in Storage under File Systems.
