Description Nandini 2020-12-18 06:37:42 MST 
Hello,

One of the user who ran a job on GPU node failed  and I am trying to find out what caused this job failure. this is the output in the log file

Slurm job error: Failed to invoke task plugins: task_p_pre launch error [2020-12-17T12:36:50.486] [15244.batch] sending REQUEST_COMPLETE_BATCH_SCRIPT, error:0 status:256

Can i know what it means by status:256 in the log file.

This is the job submission script and it works when i try to run 2nd time. I would like to know more on ths error as this happens often running different jobs.

thanks
Nandini

Comment 2 Nandini 2020-12-18 07:10:56 MST 
And also is it not possible to get full information for the finished job on the location of job submission script. I so far couldnt find?

thanks

Comment 3 Michael Hinton 2020-12-18 15:13:09 MST 
Hi Nandini,

Could you attach the slurmd log for the node, as well as the slurmctld.log?

Can you also attach your current slurm.conf?

Thanks,
-Michael

Ok, I went ahead and marked those attachments as private. I'll look into them and get back to you.

Thanks!

Comment 9 Michael Hinton 2020-12-18 16:11:51 MST 
Could you set SlurmdDebug=debug in slurm.conf, restart the slurmds, reproduce the issue, and then attach the relevant slurmd.log portion? That should give us more information about why it's failing.

Thanks,
-Michael
Comment 10 Nandini 2020-12-18 16:15:42 MST 
Will restarting slurmds will affect running jobs. What are the impact of restarting slurmd?

No, restarting the slurmds should not affect already running jobs.
Comment 12 Nandini 2020-12-19 08:22:08 MST 
But before that using failed job's id how can I check the folder where the job submission script is located. In UGE we have the option to look at full details of the failed job. In slurm I have tried all the commands that I know off and none of them would get me the information needed.

Thanks

By default, you can't access the submission script with Slurm. However, you could set up a job completion plugin to save the submission script and I think the job command. Otherwise, the temporary copy of the submission script is dropped once the job goes through.

Hi Nandini,

We can't proceed until you do what I asked in comment 9.

Thanks,

Hi Nandini,

I'm going to go ahead and close this out due to inactivity. Feel free to reopen if you want to pursue this further.

Thanks!
