Why won't my job run?
If your job shows "Eqw" or "qw" state when you run qstat. Check your job with:
qstat -j <job number>
Did your job ran but something else isn't working, get more info with:
qacct -j <job number>
Check the lines with "failed" and/or "exit_status"
If you have an "access denied" message somewhere in your job explanation, you probably have a permission problem. Your user account does not have the privileges to read from/write to where you told it (this happens with the -e and -o options to qsub often). Check if you can write to the specified directories.
To avoid permissions problems, cd into the directory on the NFS where you want your job to run, and submit from there using qsub -cwd to make sure it runs in that same directory on all the nodes.
Not a permissions problem? Maybe the nodes or the queues are unreachable. Check this with:
