Similarly, the GPU nodes can be accessed via the gpu partition. Note, that the type and number of GPUs need to be specified. More infos about the hardware specification of each node can be found in the System Overview (TODO: Link).
Partition | Nodes | Description |

smp | prod-[001-240] |

mpp | prod-[001-240] |

By default, the QOS 30min is used. It has a max. walltime of 30 minutes and jobs with this QOS get a higher priority and have access to a special SLURM reservation during working time (TODO: add details when set up), to facilitate development and testing. For longer runs, another QOS (and walltime) has to be specified. See table below. Note: long running jobs (longer than 12 hours, up to 48 hours) “cost” more in terms of fairshare.
QOS | max. walltime | UsageFactor | Priority QOS_factor |
|---|---|---|---|
short | 0:30:00 | 1 | 50 |
12h | 12:00:00 | 1 | 0 |
48h | 48:00:00 | 2 | 0 |
A short note on the definitions:

and RawUsage= cpu-seconds (#CPUs * seconds). → Jobs using the 48h QOS are twice as expensive when calculating job priorities (see Scheduling (TODO: Link)).
