Instructions for running Jupyter Notebooks on compute nodes

Usage notes:

  • nano ( is the head node of the cluster, it should not be used for any computations!
  • to connect to the cluster, ssh
  • to get access to a particular node for interactive use, use qsub, e.g.,
    • to get one GPU and one CPU core on node 7 for 1 hour for interactive use:
      • qsub -I -l nodes=nano7:ppn=1:gpus=1,walltime=3600
    • to get entire node 1 for 1 hour for exclusive interactive use:
      • qsub -I -l nodes=nano1:ppn=12,walltime=3600 

  • better yet, do not allocate nodes for interactive use, instead just submit batch jobs, see for example Job Scripts section at for details. This is a much better way to share computing resources. 
  • interactive jobs are limited to 12 hours maximum walltime per job.
  • batch jobs are limited to 96 hours
  • submit request to staff for longer batch jobs (up to 240 hours)
  • to see what’s running on the cluster, just run qstat
  • this is a shared resource, please keep in mind that other users are using it as well; do not take over the system beyond what you really need.
  • home directory is cross-mounted and accessible from all nodes
  • Current System Status:

DL frameworks

  • TensorFlow 1.10
