• 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
