MATLAB (MATrix LABoratory) and is a numerical computing environment. You can find more information on the origins of Matlab here.

Enviornment Setup

To use matlab for the batch job we will demonstrate we need to load the required module. You can do this by modifying your $HOME/.bashrc file to include the current Matlab module.

module load matlab/r2017a

In your $HOME directory create another directory to run the Matlab jobs, and add the example job from Matlab that we will modify.

razor-l1:jokinsey:~$ mkdir MATLAB-JOBS
razor-l1:jokinsey:~$ cp /share/apps/matlab/R2017a/examples/matlab_featured/MultiplePlotsExample.m MATLAB-JOBS/

Example Batch Job

To get output an output from the job we need to modify the example. At the top of the file where figure is defined set figure equal to a value so we can save it to a file later.

f = figure;

At any point after a plot is created you can save the figure to a pdf file test which will export the figure so we can view it later. You can find documentation on this here.


Once the example has been prepared, create a PBS script named matlabTest.pbs which looks like the script below to run the job.

#PBS -N matlab
#PBS -q tiny16core
#PBS -j oe
#PBS -o matlab.$PBS_JOBID
#PBS -l nodes=1:ppn=16
#PBS -l walltime=1:00:00

cp MultiplePlotsExample.m /scratch/$PBS_JOBID
cd /scratch/$PBS_JOBID

matlab -nodesktop -nosplash < MultiplePlotsExample.m
cp /scratch/$PBS_JOBID/test.pdf $PBS_O_WORKDIR

All that's left to do is submit the job.

razor-l1:jokinsey:~/MATLAB-JOBS$ qsub matlab.pbs
