Job Partitions and Sizing
Partitions
Jobs are submitted to partitions (queues), which control which resources can be used by the job and other restrictions such as wall time. Some resources can be used by jobs from more than one partition.
The partitions available are:

Job Sizing
The cluster machines have the following specification:
fury: 48 cores, 128 GB RAMhornet,dragon,gauntlet: 56 cores, 256 GB RAMmohawk: 64 cores, 256 GB RAM
The maximum number of cores which can be requested is therefore 64 cores. The minimum number is 1.
It recommended to choose the number of CPU cores based on known scaling of the problem / code, but to be a multiple of 8 where possible, to improve the allocation of resources.
