jobber examples: output options

jobber has I/O options that are similar to other programs that launch parallel processes (like mpirun or srun):

  • --label: label task output with "task_id:".
  • --label=2: label task output with "task_id.worker_id:".
  • --msgprefix: label jobber output with an own prefix.
  • ++timestamp: do not print timestamps in jobber output.
  • --iodir: generate output per task in the specified directory, files are named task_id.worker_id.out, task_id.worker_id.err, and, if needed, task_id.in.
