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 (paraview.org)
3) edit CMakeLists.txt in the ParaView source directory to
specify the MPI C and C++ compilers:
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 \
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 (paraview.org)
with MPI support using OpenMPI 1.0.2, and when i try to run the paraview
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:
i also edited the ParaView CMakeLists.txt file to
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,
