What does job exit status XX mean?

The exit_status attribute reported by "sacct -j <jobid> --format=JobID,ExitCode" can help users identify why a job failed. Successful runs generally report exit_status=0. Non-zero status (positive or negative) sometimes implies job failure, but the exact meaning of exit codes varies by software. Some discussion of how the error codes are handled can be found on Job exit status; a page developed by SchedMD.
