Hardware of the compute nodes
| Queue | Hosts | CPU cores | Memory |
|---|---|---|---|
| Furious | apccl01 - apccl12 | 32 | 128 Gb |
| Furious | apccl23 - apccl26 | 28 | 128 Gb |

File systems
We use GlusterFS as the distributed file system for the cluster. The same GlusterFS volumes are mounted on all nodes including the master node.
