The cluster is built on top of [[https://slurm.schedmd.com/|SLURM]] and is using [[https://www.lustre.org/|Lustre]] for [[internal:linux-network#directory-structure|data storage]].
  
 +Currently there are following partitions (queues) available for computing:
 +
 +| **Partition name** | **Nodes**  | **Note** |
 +| cpu-troja      | 7x CPU | default partition |
 +| gpu-troja      | 6x GPU | features: gpuram48G,gpuram40G |
 +| gpu-ms         | 7x GPU | features: gpuram48G,gpuram24G |
