Serial jobs are allocated a single CPU on a shared node with minimal capacities that satisfies other allocation criteria.

Parallel job |
|
| A job that requests more than one slot, regardless of any other constraints. | |
|
|
| Parallel jobs are allocated up to the maximum number of nodes specified | |
|
|
| by the following specifications: | |

| • SLURM[nodelist=node_list] (if specified) | |

|
| Parallel jobs and serial jobs cannot run on the same node. | |
Small job |
|
| A parallel job that can potentially fit into a single node, and does not | |

|
| explicitly request more than one node (SLURM[nodes] or | |
|
|
| SLURM[node_list] specification). | |
