General Linux

To run this software interactively in a Linux environment run the commands:

module load matlab
matlab

Several versions of Matlab are available, but the versions may be different on different platforms.To list all versions of Matlab available on the machine, type

module avail matlab

When running on the elmob nodes use this module instead:

module load matlab/R2010b
matlab

Slurm Example

module load matlab/R2019a
wget https://public.s3.msi.umn.edu/reframe/sw/matlab/script.m
matlab -nodisplay -nodesktop -nosplash -r "run('script.m'); exit;"

Parallel Test Script

The following test script demonstrates how easily Matlab loops can be parallelized with "parfor". Basic benchmarking information is included and will vary with your choice of "ppn=". Note that "cl.parpool()" autodetects the number of workers based on the value of maxNumCompThreads() in your PBS script. Or you can override the value by passing it as the first argument (e.g., "cl.parpool(4)").

cl=parcluster('local')
pool = cl.parpool()

N=50000000

tic
for i = 1:N
    A(i) = rand(1,1);
end
serial_time=toc

tic
parfor i = 1:N
    A(i) = rand(1,1);
end
parallel_time=toc

speedup = serial_time / parallel_time 
efficiency = speedup / pool.NumWorkers

exit
