I have a problem when running my jobs in array since some subjobs submitted as single jobs are completed in a shorter time. For instance, there is one job, which submitted as a single job takes 43 seconds:
resources_used.cpupercent = 298 resources_used.cput = 00:11:04 resources_used.mem = 1767396kb resources_used.ncpus = 1 resources_used.vmem = 11767892kb resources_used.walltime = 00:00:43 job_state = F
But, when submitted in array with 9 other subjobs, takes over 18 minutes:
resources_used.cpupercent = 624 resources_used.cput = 01:39:57 resources_used.mem = 1732828kb resources_used.ncpus = 1 resources_used.vmem = 11766056kb resources_used.walltime = 00:18:02 job_state = F
When I shorten the array to 5 subjobs, then it is:
resources_used.cpupercent = 144 resources_used.cput = 00:18:07 resources_used.mem = 1691420kb resources_used.ncpus = 1 resources_used.vmem = 11720892kb resources_used.walltime = 00:13:03 job_state = F
Could this be caused by some admin PBS settings?
