Hi Matt,
In that case, what would be a good or accurate way to debug the MPI
code? I'm trying to determine where the fault lies.
Thank you
Yours sincerely,

Hi,
I am trying to debug my CFD Fortran MPI code. I tried to add:
call PetscBarrier(PETSC_NULL_OBJECT); if (myid==0) print *, "xx"
to do a rough check on where the error is. xx is a different
number for each line.
I found that whenever I add this line, the code aborts with
segmentation error.
I am using the Intel compiler. Is there any error with my usage?
I don't think this makes sense since it will try to pull a
communicator out of the NULL_OBJECT.
