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 |
|
||
| ---- | --- | --- | ---- | ----- |
|
||
| Compute node | _2x_ AMD EPYC 7713 (x86_64 Milan, 64 Cores, 3.2GHz) | 512GB DDR4 3200Mhz | _4x_ NVidia A100 (Ampere, 80GB) | |
|
||
| Login node | _2x_ AMD EPYC 7742 (x86_64 Rome, 64 Cores, 3.2GHz) | 512GB DRR4 3200Mhz | | |
|
||
|
||
#### Storage
|
||
|
||
* CephFS only for `/home` -- 1 TB
|
||
* ClusterStor L300 for `/scratch` -- 224 TB usable space
|
||
* CephRBD `/local` -- 100GB
|
||
|
||
#### Node IDs
|
||
|
||
Cray user various identifies to uniquely label each node, details on this can be found on the [Crayism page](cray-conventions.html).
|
||
The table below collates these together for the current configuration:
