I just built paraview on an opensuse linux box. When I use the GUI, and a single connection it seems to work fine. But, if I try to use multiple CPUs, or run with mpi, it fails. I do have OpenMPI installed. When I first started getting the error, I googled around some and found that maybe "make install" would help (I had been running it just in the build directory). But I am getting the same error after installing. I also added my openmpi libraries to LD_LIBRARY_PATH (when I first tried to run it I had other errors about a shared library).
I did build with PARAVIEW_USE_MPI set to on. It looks as though one pvserver will run, but any additional ones finds a port in use. Clearly something is not right about how MPI is being handled, but I am not sure how to fix it. If I try mpirun, here is error I get: mpiexec -np 3 pvserver Waiting for client...

Exiting... ----------------------------------------------------------------------------- It seems that [at least] one of the processes that was started with mpirun did not invoke MPI_INIT before quitting (it is possible that more than one process did not invoke MPI_INIT -- mpirun was only notified of the first one, which was on node n0). mpirun can *only* be used with MPI programs (i.e., programs that invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program to run non-MPI programs over the lambooted nodes. ----------------------------------------------------------------------------- mpirun failed with exit status 252 And suggestions would be greatly appreciated. thanks, --Adam
