Hi I am new to slurm and I am trying to run a MATLAB function (I cannot use MDCS because that apparently is not available on one of my available HPC clusters)

I think I am having trouble with understanding the appropriate notation for running a script vs a function using slurm.

These are the two pieces of code that I have seen:

matlab -nodisplay < multi_parfor.m

and...

matlab -nodesktop -r "multi_parfor.m"

I was wondering if anyone could explain how to do this, and maybe make a comment on the use for each of the above lines of code (is one for a script and one for a function? etc).

Thank you in advance

You can pass the input arguments for a funtion like this:
srun matlab -nodisplay -singleCompThread -r "FunctionFileName(INPUTArg1,INPUTArg2,INPUTArg3)"
If it is just a script, and not a function, this is how you would write it:
srun matlab -nodisplay -singleCompThread -r "ScriptFileName"
Compute Canada documention has a clear outline on how to write a Slurm submission script to submit a MATLAB job:
https://docs.computecanada.ca/wiki/MATLAB
And this matlab documentation outlines the syntax/commands of the line above:
