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:
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 \
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 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:
i also edited the ParaView CMakeLists.txt file to contain:
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,
