Hi L-A,

You might have been confused by original response. I mentioned only "-Mprof=mpi,func" since it works with or without "-Mmpi". I didn't intend for you to think that "-Mmpi" needed to be removed. The two flags are not dependent upon each other. All "-Mmpi" does is add the default MPICH libraries at link time which could also be achived by using "mpicc" or adding the MPICH libraries directly on the link line.

Hi Mat,

I think that the 2 similar systems where I do my testing could have a config problem. But that's what i got.

pgcc -Mmpi :
MPI only, no profile (ok!)

pgcc -Mmpi -Mprof-mpi,func :
MPI, I can look at the function profile for each process but i don't see the messages and byte count

pgcc -Mprof-mpi,func
MPI, i can look at the function profile for each process and I see the messages and byte count
(ok)


All I try to explain is, if that behavior is common someone should change it. The command 'pgcc -Mmpi -Mprof-mpi,func' and 'pgcc -Mprof-mpi,func' should give the same binary.

this is the different dryrun output (only the diffs):

(-Mmpi and -Mprof=mpi,func)
