This documentation shows basic Slurm configuration and options needed to run jobs in the Merlin7 cluster.
Infrastructure
Hardware
The current configuration for the test phase is made up as:
- 9 nodes for the PSI-Dev development system
- 8 nodes were meant for baremetal and k8s
- 1 login node
| Node | CPU | RAM | GRES | Notes |
