====== Partitions ======

**Partition** == **Queue**

SLURM allows the definition of different partitions. A partition is a subset of all the nodes in the cluster. Partitions are not mutually exclusive, so a node can belong to multiple partitions. Every compute node is assigned to one or more partitions.

Our cluster has 4 different partitions:

  * **standard** 
    * The default queue. Contains the 31 standard compute nodes (at least 128GB RAM, at least 16 cores). No time limit.
  * **gpu** 
    * Contains the GPU machines only. No time limit. node91 has two (old) Nvidia K20m GPUs. node94 has an Nvidia V100 with 32GB of RAM.
  * **bigmem** 
    * Contains big memory machines only (512GB or 768GB, 32 cores). No time limit.
  * **short** 
    * Contains all nodes, including gpu and bigmem, but has a 5 hour time limit, and jobs in this queue have a lower priority than jobs in the other queues. The short queue allows users with quick-running jobs to make use of all the cluster nodes without holding up users who need the special purpose (bigmem or gpu) nodes too much.

**Standard**, **gpu**, and **bigmem** have no time limit.
