User Guide
Documentation for the CHPC systems starts with the CHPC Quick Start Guide. Read it, but note the differences below which are specific to the studentNN accounts you are using.
Student Accounts

studentNN - Your project is:
Wchpc - Your queue is:
R522145 - Your PBS group is:
training
Interactive Session
A user can not simply ssh onto a compute node because you don't know which ones are not in use by a currently running job. But the PBSPro scheduler does know. So we ask the scheduler for an interactive job which gives us a login shell on a compute node:
qsub -I -P Wchpc -q R522145 -W group_list=training
