Hi
I'm trying to run a code on a remote cluster and I would like to check that matlab uses all the cores I've requested (up to 12). From the time it takes to run, I think only one is used.
Does anybody have a simple script that I could run on the cluster (without hpc module) to check if the problem comes from my script itself or something else ?
Thanks
Stéphane

Try running the following code. Set N to the number of cores you want to run on. This should take ~4 seconds to run.
N = 12;
parpool(N)
tic
parfor idx = 1:2*N
pause(2)
end
toc
