Hi Yan,

I understand you are facing issue with running a matlab job on your HPC Cluster.

I've noticed a couple of potential issues in the script you've provided. After reviewing several blogs about sbatch and mpirun, it seems that the MATLAB module isn't being loaded in your script. When you want to run a MATLAB script in batch mode, it's essential to use the -r flag to instruct MATLAB to run the specified script. Additionally, the -nodisplay and -nosplash flags are crucial to prevent MATLAB from attempting to use a graphical user interface.

Here are some resources that might be helpful in addressing your issue:

• New Mexico State University HPC - MATLAB
• NTNU HPC - MATLAB and MPI
• Princeton University Research Computing - MATLAB

Typically, MATLAB manages its own parallel computing environment, which usually doesn't require the use of mpirun, unless you're specifically leveraging MPI-based features in MATLAB.

I hope this information proves to be useful for you!

Hi Bassem,

I understand why you might think this is an AI-generated prompt, but I assure you these are standard steps that I personally thought would help Yan in debugging the issue. My sole intention was to assist him in navigating the problem effectively, hence the detailed response.

Dear Yan,

I know this posted 2 years ago, but I hope you have removed the space in

MATLAB= /cm/...

In Bash, white space is also functional (in a different way from Python). It needs to be like:

MATLAB=/cm/...

No space before and after the equal sign ("=").

And also, call MATLAB like this:

$MATLAB -r "your_script.m; exit"

Best,
