Today I’d like to introduce a parallel computation skill in Matlab.
I also heard that the use of parallel computation in Matlab is very easy. But it was better than my expectation. Wonderful!!
You need to know the usage of SPMD. It is pretty easy.
First let’s the code, you can also download this file in the attachment, click <here>.
The result is the below
Starting matlabpool using the ‘local’ configuration … connected to 4 labs.
Elapsed time is 120.482356 seconds.
Sending a stop signal to all the labs … stopped.
Elapsed time is 167.796932 seconds.
Because, I did many other works in the calculation time, Its result is not very fast, The slowest CPU core determined the final computation time. But its performance is really good if you have more than 4 multi cpu cores.
I wish this post can help your understanding about the use of SPMD in Matlab.
if you have any question, please leave me a comment below.
