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 in.

2) download the ParaView source (paraview.org)

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 \
/path_to_paraview_src/

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):

make

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...
