Is there any tool to help me setup syntactically correct qsub command?

Yes, there exists an online tool qsub assembler.

Basically it is a form with a drop-down menu for every PBS resource type.

The only thing you need to do is to setup the value of selected resource(s) and click on the "Find machines" button.


As a result you will get

  • a qsub command in a single-line format (to paste on CLI)
  • dtto in a multi-line format of #PBS directives (to paste to the top section of batch script)
  • a list of machines that comply with your criterions


The common confusion is that users try to remove the whole scratch directory


while they are allowed to remove only the content of the scratch directory:

rm -rf $SCRATCHDIR/*

The empty scratch directory will be removed automatically after some time.
