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

If your MPI calls is NOT within OpenMP directives, MPI does not even

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.
/bin/mpif77 -o foo foo.f -L/lib -lmpi_f77 -lYou

If the app sends message to its
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.

With above modification and MPI_Finalize in the main(). I was able to run
the program with OpenMPI (as well as mpich2). Hope this helps.

Hi George,
Just out of curiosity, what version of OpenMPI that you used works fine
with Jeff's program (after adding MPI_Finalize)? The program aborts with
either mpich2-1.0.5p4 or OpenMPI-1.2.3 on a AMD x86_64 box(Ubuntu 7.04)
because MPI_Comm_rank() is called with MPI_COMM_NULL.
With OpenMPI:

Never tried this myself, but this test could work

trace_sample is a sample TRACE-API implementation for SLOG2, e.g. for
people who write their own trace and to generate

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.

This is not a bug just wonder if this can be improved. I have been
running openmpi linked program with command
/bin/mpirun --prefix \
--host A -np N a.out
My understanding is that --prefix allows extra search path in addition to
