Jobs using specific installed software

The FAQ (FAQ - Using third-party software) includes examples of how to best run certain software including:

FAQ - How do I use Matlab on the HPC clusters?

FAQ - How do I use Gaussian on the HPC clusters?


Options to request compute resources:

  • -l walltime=walltime
    Maximum wallclock time the job will need. Default is 1 hour. Walltime is specified in seconds or as hh:mm:ss.
  • -l mem=memory
    Maximum memory per node the job will need. Default depends on queue, normally 2GB for serial jobs and the full node for parallel jobs. Memory should be specified with units, eg 500MB or 8GB.
  • -l nodes=num:ppn=num
    Number of nodes and number of processors per node required. Default is 1 node and 1 processor per node. The :ppn=num can be omitted, in which case (at NYU HPC) you will get full nodes. When using multiple nodes the job script will be executed on the first allocated node.
  • -q queue
    Submit to a specific queue. If not specified, Torque will choose a queue based on the resources requested.

    A job submitted without requesting a specific queue or resources will go to the default serial queue (s48 on Mercer) with the default resource limits for that queue

    Requesting the resources you need, as accurately as possible, allows your job to be started at the earliest opportunity as well as helping the system to schedule work efficiently to everyone's benefit.
