Hi everybody,

I was installed the parallel package, then loaded and finally run the the
following simple code on the latest Octave (9.3.0):

% Simplified stress test
num_cores = nproc();
test_duration = 60;

disp(['Starting stress test on ', num2str(num_cores), ' cores']);
disp(['Duration: ', num2str(test_duration), ' seconds']);

% Simplified stress function
function result = stress_task(~)
    A = rand(500, 500);  % Smaller matrix
    for i = 1:50
        A = A * A;
    end
    result = sum(A(:));  % Dummy result
end

try
    tic;
    pararrayfun(num_cores, @stress_task, 1:num_cores, "VerboseLevel", 1);
    disp('Stress test completed.');
catch err
    disp('Error occurred during parallel execution:');
    disp(err.message);
end

But I got this error message:

Starting stress test on 4 cores
Duration: 60 seconds
execution error
Error occurred during parallel execution:
__parcellfun_get_next_result__: could not receive result
>>

How can I resolve this problem?

Thank you!
