Job output

By default, Slurm will generate a single job output file in format slurm-JOBID.out, containing the STDOUT and STDERR streams produced by the job.

The naming and merging of the files can be changed using job script options, and we highly recommend you give your Slurm jobs a name and then manually define your job output file(s) naming scheme to match, to avoid all your output files starting with slurm-.

You can change how output files are named using job script options. We recommend naming your Slurm jobs and defining custom output files to avoid the default slurm- prefix.

See the official Slurm filename pattern documentation for more information about the Slurm replacement symbols (percent sign % followed by a letter) used in the examples below.

Quoting job names with spaces

Slurm supports job names with spaces providing the -J (or --job-name) parameter is quoted (for example, -J "test job") however, we recommend replacing spaces with underscores or hyphens if possible.

Single combined job output file

For a single output file (which would be named jobname.oJOBID):

#SBATCH -J jobname
#SBATCH -o %x.o%j

Example for a job called jobname with the job number 1234567:

jobname.o1234567

Separate job error and output files

For separate output files for STDOUT and STDERR (which would be named jobname.oJOBID and jobname.eJOBID respectively):

#SBATCH -J jobname
#SBATCH -o %x.o%j
#SBATCH -e %x.e%j

Example for a job called jobname with the job number 1234567:

jobname.e1234567  (STDERR)
jobname.o1234567  (STDOUT)
