This shouldn't be calling MPI_Finalize() as the finalizedExternally argument is 1 and in vtkMPIController::Finalize(): if (finalizedExternally == 0) { MPI_Finalize(); } So my guess is that it's being invoked elsewhere. >> >> ... >> >> #ifdef PARAVIEW_USE_MPI >> if (vtkProcessModule::FinalizeMPI) >> { >> MPI_Barrier(MPI_COMM_WORLD); <-------------------------barrier after >> mpi_finalize >> MPI_Finalize(); <--------------------------------------second >> mpi_finalize >> } >> #endif I've made a patch which should prevent this second of code from ever being called twice by setting the FinalizeMPI flag to false after calling MPI_Finalize(). Can you take a look here: http://review.source.kitware.com/#/t/1808/ and let me know if that helps the issue. Otherwise, would you be able to set a breakpoint on MPI_Finalize() and get a backtrace of where it gets invoked for the second time? That would be very helpful in tracking down the problem.
