Running jobs on Nemo

NEMO uses MOAB for submitting jobs, so you can use the general documentation on our central wiki pages.

But because of different hardware and use cases, the queues and classes have  different definitions. Currently there are only two standard queues, compute and memory. All compute nodes have 8 cores, only one test node has 16 cores (s. hardware).

PLEASE DO NOT SPECIFY A QUEUE NAME WHEN SUBMITTING JOBS

Example:

msub -l nodes=1:ppn=8,walltime=1:00:00:00 myjob.moab

Queues

Defaults:

  • Walltime: 12:00:00
  • Procs: 1
  • Mem: 1GByte

Queues/Classes:

  • compute (all nodes without HP)
    • Max. Node: 16
    • Max. Walltime: 96:00:00
  • memory (only HP nodes, currently not available)
    • Max. Node: 1
    • Max. Proc: 32
    • Max. Walltime: 96:00:00
    • Default Mem: 32GByte

Q&A

I get the following error:

ERROR:    cannot migrate job '123' to PBS - qsub: submit error (Access to queue is denied MSG=queue accepts only routed jobs, no direct submission...)

Answer:

You have specified a queue name on submission, on submission, e.g. '-q compute'. Please remove this statement, since the scheduler does this for you.
