If you want to debug this on BGP, you could set BG_COREDUMPONERROR=1
and look at the backtrace in the light weight core files
(you probably need to recompile everything with -g).

Hi lagoun,
The error message looks like from MPICH2. Actually, it seems the code
was linked with mpich2 library but was compiled with mpich-1 header file.
You should use MPI wrappers, i.e mpicc/mpif90..., provided by your chosen
MPI implementation.

I don't think you can declare a function with a fortran parameter:
subroutine testsubr(MPI_COMM_WORLD,ireadok)
1) If you've already included mpif.h with in testsubr(),
you don't need the 1st argument above.
2) If you don't have mpif.h in testsubr(), the 1st argument
could be MPI_comm. In
MPI_COMM_WORLD is defined by a parameter statement, so it
is a fortran contant. The following f77 program fails to compile.

Try using "mpecc -mpicc=" to compile your C++ program.
"mpicc -mpilog" is only available in the MPICH (not MPICH2 which provides
mpicc -mpe=mpilog). Non-MPICH(2) based implementation needs to use
mpecc instead to enable MPE.

To compile fortran application with MPE, you need Fortran to C wrapper

What errors did you see when compiling MPE for OpenMPI ?

Hope I didn't misunderstand your question. If you implement
your profiling library in C where you do your real instrumentation,
you don't need to implement the fortran layer, you can simply link
with Fortran to C MPI wrapper library -lmpi_f77. i.e.

Hi all,
Say I've created a number of child processes using MPI_Comm_spawn:
int num_workers = 5;
MPI_Comm workers;

MPI_COMM_SELF, &workers, MPI_ERRCODES_IGNORE);

MPE is not part of OMPI. You can download MPE from
http://www.mcs.anl.gov/perfvis (the latest is the beta at
ftp://ftp.mcs.anl.gov/pub/mpi/mpe/beta/mpe2-1.0.7rc3.tar.gz)
Then follow the INSTALL and install MPE for OMPI.

I just built the related mpe2's subpackage, slog2sdk, on a AMD64 (Ubuntu
6.06.1) with gcc-
nt. The change should make things easier for
typical MPI users.
