Parallel computing toolbox setup

Is there any additional configuration need to be done inorder to use parallel computing toolbox in default cluster (local)? I have 12 workers in parallel pool (local ) and automatically create a parallel pool box checked.

With this default cluster I tried to use parfor, it doesn't work (showing busy for long time- no sign of finishing the job).

Hi ,

Can you try out a simpler example and check, as shown below:

tic
n = 1000;
A = 500;
a = zeros(1,n);
%Without parfor
for i = 1:n
    a(i) = max(abs(eig(rand(A))));
    fprintf('%d %d \n', i, a(i));    
end
toc

Elapsed time : 98 seconds

tic
n = 1000;
A = 500;
a = zeros(1,n);
%With parfor
parfor i = 1:n
    a(i) = max(abs(eig(rand(A))));
    fprintf('%d %d \n', i, a(i));    
end
toc
