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 **
