Hello,
I want to know if I need to make any modifications to my source code to replace
MPICH-1.2.6 with Openmpi-1.2.7?? I mean are the function interfaces exactly the
same in both MPISH and OMPI?? please let me know.
Thanks.
My code was working perfect when I had it with MPICH now I have replaced that
with OMPI. Could that be the problem?? Do I need to change any part of my
source code if I migrate from MPICH-1.2.6 to OpenMPI-1.2.7?? Please let me know.

Ok. I noticed that whenever in my code, i use an MPI fucntion that has
"OMPI_DECLSPEC" in front of it in mpi.h , I get this segfault error. Could
some one please tell me what is "OMPI_DECLSPEC"?? is it a macro that I need to
enable ?!?
forexample, in MPICH the function getsize in mpi.h looks l
Are you sure that you have matching versions of the MPI library and
mpi.h file ? Open MPI and MPICH have different internal types for the
opaque MPI objects (such as MPI_Comm). If you have mismatching mpi.h
and mpi library, you'll transmit those as integer to the library while
it is expecti
Yes I am using openmpi mpicc and mpic++ to compile my code, and I only have
openmpi's lib directory in my LD_LIBRARY_PATH. to make sure that I am including
the mpi.h of openmpi, i added this line to my source code
#include "/opt/openmpi/1.2.7/include/mpi.h"instead of only saying
#include "mpi.h
I have both openmpi and MPICH on my cluster, the problem is that mpi.h of MPICH
is in /usr/local/include and I dont have permission to rename or remove it from
there. In my source code I am including the mpi.h of openmpi and this works
fine, but then mpi.h itself includes mpicxx.h which it again
Just specify where each individual MPI distribution's stuff is on the
command line when you compile with mpicc *.c -I$MPICH_HOME/include or
mpicc *.c -I$OPENMPI_HOME/include where the "HOME" directories were
specified with --prefix= when you installed. Hope this helps. This
works for me. Hope th
I have tried this, but didn't help :-( could any one help please???
