One possible datapoint: on the node where the job ran, there were two slurmstepd processes running, both at 100%CPU even after the job had ended.

External.

Hi, all:

I'm trying to understand why a job exited with an error condition. I think it was actually terminated by Slurm: job was a Matlab script, and its output was incomplete.

Here's sacct output:

               JobID    JobName      User  Partition        NodeList    Elapsed      State ExitCode     ReqMem     MaxRSS  MaxVMSize                        AllocTRES AllocGRE

Thanks in advance,
