scrontab manages Slurm crontab files for scheduling recurring batch jobs on HPC clusters. It uses standard cron time specifications (minute, hour, day of month, month, day of week) combined with Slurm sbatch directives via #SCRON comment lines.Lines starting with #SCRON define sbatch options for the single following crontab entry; options reset between entries. Unlike traditional crontab, user environment variables are not inherited. Jobs are automatically submitted to the Slurm scheduler at specified intervals.
