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

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
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
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

forexample, in MPICH the function getsize in mpi.h looks l
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.

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.
