Also known as a task array or an array job, a job array is a way to submit a whole set of jobs with one command. The individual jobs in the array are distinguished by an environment variable, $SLURM_ARRAY_TASK_ID
, which is set to a different value for each instance of the job.
sbatch --array=0-7 ... # $SLURM_ARRAY_TASK_ID will take values from 0 to 7 inclusive sbatch --array=1,3,5,7 ... # $SLURM_ARRAY_TASK_ID will take the listed values sbatch --array=1-7:2 ... # Step-size of 2, does the same as the previous example sbatch --array=1-100%10 ... # Allow no more than 10 of the jobs to run simultaneously
