Many thanks for following up to the list with this information.

        Subject: Re: [OMPI users] ParaView runtime problem with openmpi
        to successfully build ParaView with OpenMPI support in Linux:
        1) compile OpenMPI and add openmpi/bin/ to the top of your PATH
and add openmpi/lib/ to the top of the LD_LIBRARY_PATH environment
variable. this is in my .cshrc so they are always set whenever i log
        2) download the ParaView source (
        3) edit CMakeLists.txt in the ParaView source directory to
specify the MPI C and C++ compilers:
        SET(CMAKE_C_COMPILER mpicc)
        SET(CMAKE_CXX_COMPILER mpicxx)
        4) make a ParaView build directory and cd to the new dir
(ParaView requires out-of-source builds)
        5) configure the ParaView make using cmake as follows:
        cmake -DVTK_USE_MPI:BOOL=ON \
        -DVTK_MPIRUN_EXE:FILEPATH=/path_to_openmpi1.0.2/bin/mpirun \

        6) once the configure is complete (lots of text dumped to the
screen), you should be able to make the binaries (from within the
paraview build directory):
        Now you can run ParaView in parallel mode using:
        mpiexec -n NP /path_to_paraview_build/bin/./paraview
        where NP = desired number of processes.
        happy parallel volume rendering...

                i have compiled a program called ParaView (
with MPI support using OpenMPI 1.0.2, and when i try to run the paraview
executable using
                mpiexec -n 4 paraview
                miprun -np 4 paraview
                instead of having one paraview window open with parallel
support, there are 4 paraview windows opened, none of which are running
with parallel support. attached are the ompi_info and config.log files.
below is the text of the cmake call i used to configure paraview:
                cmake -DVTK_USE_MPI:BOOL=ON
                i also edited the ParaView CMakeLists.txt file to
                SET(CMAKE_C_COMPILER mpicc)
                SET(CMAKE_CXX_COMPILER mpicxx)
                both compiler wrappers are on the top of my PATH. also,
as far as PATH goes, yes, i am certain that the mpiexec and paraview
binaries are the ones i think they are ( i.e. when I WHICH MPIEXEC it
only shows the one i compiled locally, etc).
                anyone have any insight on this? for the record, when i
compile paraview with MPI support using mpich2 (1.0.3), and then do
mpiexec calling that version of paraview, i get the expected behavior (
i.e. one paraview window running with parallel support).
                thanks in advance,
