Hi Expert,
Env:
OS : Centos 7.7
Kernel: 3.10.0-1062
PBS Version: 19.1.3
question:
1. I’ve submitted an array job, but the stdout and stderr come after all of the jobs are finished. how to make the stdout and stderr come after sub-jobs are finished?
2. If there is an error in one of the sub-jobs, there is not much information on qstat -tf jobid[index], is there any good way to debug one of the sub-jobs ?

PBSpro, by default, spooks output and error logs into a directory on the node where the job is running. At the end of the job the output is returned to the the submission host via scp in the directory where the user ran the qsub command. The -o and -e options allows the user to specify an alternate directo…

Please try these commands:
tracejob jobid[index[# tracejob 111[1]
$PBS\_EXEC/unsupported/pbs\_dtj jobid[index] # $PBS\_EXEC/unsupported/pbs\_dtj 111[1]
Hope this helps
