CICS HPC Rain Cluster - Matlab

To access matlab on the rain cluster. First login to the head node:

$ ssh rain.umd.edu

Next request an interactive session from a compute node:

[rreese@rain ~]$ qrsh

If you want to request more slots (cores) you can use the following:

[rreese@rain ~]$ qrsh -pe orte 16

NOTE: The cluster has a maximum of 64 cores at the time of this writing.

You can verify the number of slots you are using by issuing qstat:

[rreese@compute-0-0 ~]$ qstat
job-ID  prior   name       user         state submit/start at     queue                          slots ja-task-ID
-----------------------------------------------------------------------------------------------------------------
    455 0.55500 QRLOGIN    rreese       r     03/13/2017 12:05:44 all.q@compute-0-0.local           16      

This will place you on one of the available compute nodes. You can now execute matlab:

[rreese@compute-0-0 ~]$ matlab
