Trying to capture the build summary using ert_make_rtw_hook

Upgraded to R2022b and the diary does not capture the build summary that is output. I moved my sldiagviewer.diary('off');to the exit case of the hook, but I want my top model codegen log to contain the build summary. I noticed that if I turn off the parallel pool I can capture the build summary, but with the parallel pool turned on no summary gets printed to my diary file. Any ideas? I can't seem to programatically turn the parallel pool off before codegen.

Hi Dawn,

Consider the following approaches to capture the build summary:

• Wrap everything inside your “parfor” in a function. Then you can create an “if” condition to run the “parfor” loop only when the “Parallel” flag is set to 1. This will enable you to edit and debug your code in the function and before codegen you can set the “Parallel” flag to 0. Belos is a sample code snippet to achieve this:

if Parallel 
    parfor 1:N 
        output = function(..) 
    end
else 
    for 1:N 
        output = function(..) 
    end
        
end

• Instead of “parfor” you can use “parfeval” function. This allows you to use the “Diary” property of each “parallel.Future” instance which you can log according to you needs.
