Rules on Zeus cluster

  • Using access machine for performing calculations is strictly prohibited. Administrators will interrupt such processes without warning.
  • In case to compile the program, please use command qsub -I -q l_interactive -l nodes=1:ppn=1
    This will log you on the compute node, where you should perform program compilation.
  • If you want to perform computations it is essential to pass your grant ID using "-A" parameter while using qsub command or in PBS script. Detailed infrormation about grants can be found here.
