how can I get details about the functions called inside parfor in a profile summary report?

Hi

when I run profiler for a code which contains a parfor, the profiler report shows only the total time parfor takes and not the number of times a function or statements inside a parfor are called or the time taken by them. How do I get this information? The function and statements inside parfor are in grey in the report.

Thanks Nadia

This is rather non-obvious, but you can use mpiprofile, like so:

spmd, mpiprofile('on'); end
parfor
  ...
end
spmd, mpiprofile('viewer'); end

Thank You, This gives information about each worker. But now I am not able to get profile for the other functions called outside of parfor. Is it possible to get both the informations(for functions outside parfor and the workers) in one report?

Unfortunately it isn't currently possible to view both at the same time. (You can use the programmatic API to both profile and mpiprofile to collect the information simultaneously)
