Program execution on LIGER with srun

  • If invoked from within salloc shell or sbatch script (i.e. within an existing job allocation), srun launches application on compute nodes
  • Otherwise, srun creates a job allocation (like salloc) and then launches application on compute nodes
  • By default, srun uses entire job allocation based upon job allocation specification (from salloc or sbatch)
  • srun can use a subset of the job's resources
  • Thousands of job steps can be run serially or in parallel within the job's allocation

Command srun

Run a parallel job on LIGER managed by Slurm. If necessary, srun will first create a resource allocation in which to run the parallel job.
