MATLAB: How to save the mpiprofile report

Question

Hi

how do you save the report for parallel profiler? profsave does not give the complete details as a mpiprofile viewer. Is there any other way to save report?

Answer 1

One way I figured to do something similar is the following.

I am assuming you are using "pmode" because as far as my understanding goes, you need to run on "pmode" to run mpiprofile.

So this is how it goes.

• Saving

1. Save the mpiprofile info inside each worker(or it is often called lab from my understanding).

mpiprofile mpistruct;

2. Then you transfer to the client using the following command

pmode lab2client mpistruct;

3. Then save the mpistruct into a .mat file

save('mpistruct');

• Loading

When you are trying to view the mpiprofile result:

1. Load the mpi file

load('mpistruct.mat');

2. Run mpiprofile viewer

mpiprofile('viewer', mpistruct);

This should pop up the browser.

Note. Above code was tested with 2015b.
