Description IDRIS System Team 2022-06-01 08:21:31 MDT

Hello,

We have noticed that the "--jobid" option of the "srun" command does not allow using job id formatted as "jobArrayID_jobArrayIndex" although it is shown this way by default by the "squeue" command.

This means that one has to use either the "scontrol show job" command or specific "squeue" option to convert the "job array format" to the integer job id.

It would be a great addition if the "job array format" could be accepted by "srun --jobid".

Best regards.

Thank you for this request for enhancement. This does have merit, though I can not promise a resolution or release version at this time. We will discuss this internally and let you know what we decide regarding this request.

Hi,

Just wanted to let you know that we allocated some resources to develop the suggested feature. It has been already checked in and will be available upon next 23.02.0rc1 release!

    Allow "srun --jobid" to work with job array ids.
    
    E.g., now supports "srun --jobid=12_1" without issue.

    Add jobid to job_step_create_response_msg_t.
    
    For job array tasks the underlying jobid will be needed for further srun
    communication with the slurmd as part of the launch.

    Add array_task_id to job_step_create_request_msg_t.
    
    Set to NO_VAL when unpacking from older clients to avoid issues with
    backwards compatibility.

Thanks for your feedback,

Oscar
