Example Script of using 20 workers:
%%%% parpoolexample.m START %%%%%
n=20
p = parpool('local',n);
poolobj = gcp('nocreate'); % If no pool, do not create new one.
if isempty(poolobj)
poolsize = 0;
else
poolsize = poolobj.NumWorkers
end
tic
ticBytes(gcp);
n = 1024;
A = zeros(n);
parfor (i = 1:n)
A(i,:) = (1:n) .* sin(i*2*pi/1024);
end
tocBytes(gcp)
toc
delete(p)
%%%% parpoolexample.m STOP %%%%%
If the script is run without the steps mentioned in Running_Parallel_Jobs, you will run in to an issue where the local pool will start but wouldn't initialize the workers themselves.
- Create this parpoolexample.m before going through the steps mentioned **
