Hello,

If your problem is embarrassingly parallel (ie you run your simulations many times independently for different random matrices), you might speed up the overall simulation by running more than one instance of scilab in parallel.

Hello,

A priori, there is no reason why your calculation should use more than one CPU core, which explains why you see only 1/8=12,5% CPU use.

I am using 6.00 for windows.
I am doing a simulation using a random number matrix with a huge size. The
size of the random matrix is 10 ^ 4 x 25000.
I am using a PC equipped with 8 cores and 16 threads.
It takes a considerable time to finish the simulation, but CPU utilization is as low as 10-20%. Is there any way to increase the CPU usage and finish
the calculation sooner?
The loop is not used. I am using matrix functions.
I also considered parallel computing, but it is said that it can not be used
on windows.

Best regards.
