Using SRUN command

The "srun" command is used to run interactive jobs on the compute nodes of the HPC, The following example will run "matlab" on the compute node of the cluster:

$ module load matlab/r2014b
$ srun matlab

MATLAB is selecting SOFTWARE OPENGL rendering.

In example above we are loading the matlab module from the public software and then executing matlab as interactive job with the srun command, you can see in the output that you work with matlab interactively from matlab command line.

With "srun" command you can run jobs with a lot of different allocation options like assigning number of nodes for the job, assigning how many tasks to use, how many tasks to use per node, how many CPU's to use per task and more. Use the "man srun" command to see all the possible options.
