[BUG] Max number of CPUs per task is limited by the submission node

[ziw-liu]

These lines counts the CPUs on the node where the job is submitted:

recOrder/recOrder/cli/parsing.py

Lines 88 to 96 in 6c70732

	# TODO: this setting will have to be collected from SLURM?
	def processes_option(default: int = None) -> Callable:
	def check_processes_option(ctx, param, value):
	max_processes = mp.cpu_count()
	if value > max_processes:
	raise click.BadParameter(
	f"Maximum number of processes is {max_processes}"
	)
	return value

This is not needed with submitit, since SLURM will reject job submission if requested CPUs per task is more than what's available in the cluster.
