If you need assistance, please go to the support query page. However, before you do that, please ensure that you have crucial information available, and include it in your submission.

Here are some things to try:

• PBSPro has replaced Moab as the job scheduler. msub does not work any more, you need to use qsub.
• The syntax of a PBSPro job script is similar to that of a Moab script, but not identical. Please look at the examples on the Wiki.
• PBSPro syntax is also not identical to PBS
