The batch or job scheduling system on PALMA-II is called SLURM. If you are used to PBS/Maui and want to switch to SLURM, this document might help you. The job scheduler is used to start and manage computations on the cluster but also to distribute resources among all users depending on their needs. Computation jobs (but also interactive sessions) can be submitted to different queues (or partitions in the slurm language), which have different purposes:
Partitions

requeue*
If your jobs are running on one of the requeue nodes while they are requested by one of the exclusive group partitions, your job will be terminated and resubmitted, so use with care!
