• turm - interface for the Slurm Workload Manager - LinuxLinks

  turm obtains information about jobs by parsing the output of squeue. The reason for this is that squeue is available on all Slurm clusters, and running it periodically is not too expensive for the Slurm controller (particularly when filtering by user). In contrast, Slurm’s C API is unstable, and Slurm’s REST API is not always available and can be costly for the Slurm controller. Another advantage is that we get free support for the exact same CLI flags as squeue, which users are already familiar with, for filtering and sorting the jobs.
