Steps to run Matlab
Simple Matlab Test
These instructions NOT use the distributed licenses available on cheaha and will be restricted to a single cpu. See the next section for an example using the distributed computing license.
Set up your environment with the command:
module load mathworks/matlab
As a test, you can run MatLab and access your license server with
matlab -c port@license-server -nodesktop -nojvm -r "rand, exit"
For example:
module load mathworks/matlab
matlab -c 27000@licserver.uab.edu -nodesktop -nojvm -r "rand, exit"

To get started, type one of these: helpwin, helpdesk, or demo.

This will start matlab without a graphical display and without Java support. This is good just to verify things work, but do not run any significant computations on the Cheaha head node.
MatLab computational work needs to be run on the compute nodes by submitting a job submission script to the SGE scheduler
You can create a simple single cpu SGE script with (script name "matlabtest.qsub"):
#!/bin/bash #$ -S /bin/bash #$ -cwd # #$ -N testMatLab #$ -l h_rt=00:10:00,s_rt=00:08:00 #$ -j y # #$ -M YOUR_EMAIL_ADDRESS #$ -m eas # module load mathworks/matlab #$ -V matlab -c port@license-server -nodisplay -nojvm < matlab-script
Then submit the script to the scheduler with
qsub matlabtest.qsub
Check on it with qstat.
qstat -u $USER
