 In your job script, leave ''%%--nodes=1%%'', but set ''%%--cpus-per-task=4%%'' in order to get four cores allocated to your job. You can automatically set it in the right way by reading the requested number of cores through an environment variable that is set by the scheduler: In your job script, leave ''%%--nodes=1%%'', but set ''%%--cpus-per-task=4%%'' in order to get four cores allocated to your job.
