--cores=N

Set the total number of cores.

--tasks-per-node=N

Set the number of tasks per node to run.

--gpus-per-node=N

With --nodes, request a specific number of GPUs per node.

--tasks-per-core=N

Force a number of tasks per core. Note that this will run N tasks per allocated core. If nodes are exclusively scheduled by configuration or use of the --exclusive flag, then this option could result in many more tasks than expected. The default for this option is effectively 1, so it is useful only for oversubscribing tasks to cores for testing purposes. You probably don't want to use this option.
