| After entering into the workgroup, GPU nodes can be requested through an interactive session using ''salloc'' or through batch submission using ''sbatch''. An appropriate partition name (such as a workgroup for running or ''devel'' if you need to compile on a GPU node) and a GPU resource and type has to be mentioned while running the command as below. | After entering into the workgroup, GPU nodes can be requested through an interactive session using ''salloc'' or through batch submission using ''sbatch''.

| Any user can employ a GPU by running in the ''standard'' partition, however keep in mind jobs can be preempted and would require [[abstract:caviness:runjobs:schedule_jobs#handling-system-signals-aka-checkpointing|checkpointing]] as part of your batch job script. The interactive session example below requests any node with a GPU v100, 1 core and 1 GB of memory (default values if not specified) on the standard partition. | Any user can employ a GPU by running in the ''standard'' partition, however keep in mind a GPU type **must** be specified, jobs can be preempted and would require [[abstract:caviness:runjobs:schedule_jobs#handling-system-signals-aka-checkpointing|checkpointing]] as part of your batch job script.
