Useful ssh commands on Datarmor or other supercomputers

When you run simulations on Datarmor, all the simulation files will normally be stored in isis-tmp in your home directory (see Datarmor configuration).

Look at the job queue

  $ qstat

Look at the status of a job

  $ qstat –f JobID

For example:

  $ qstat –f 1234567[].service0

Read the simulation log

If a simulation fails, then the log will be found in the file simulation-sim…-output.txt. To read this file:

  $ cat simulation-sim…-output.txt

Rerun simulations within a simulation plan

If certain simulations (for example simulations 5 to 10) within a plan need to be re-run, they can be submitted directly:

  $ qsub –J 5-10 simulation-sim…-script.seq

Recovering results that have not been returned

If the simulation has completed correctly but the results have not been returned, the simulation file, simulation-sim…-result.zip, can be recovered by copying it to the transfer server.

  $ cp *-result.zip /home/navidad/partages/echange/Fred
