I am having quite peculiar issues with running paraview in parallel on Mac OS. I’ve downloaded the 5.8.0 version of paraview and launched without any difficulties. I have an 8-core MBPro and so I tried to launch the MPI autostart, which spawned 8 separate processes of pvserver and I was able to do my work without any problems.
However, while closing paraview, the spawned pvserver applications would be still running, and so I had to forcefully close them. Since then, if I try to autostart paraview with MPI support, this is the message I receive:
Generic Warning: In /Users/kitware/dashboards/buildbot-slave/a64f5607/build/superbuild/paraview/src/Remoting/ServerManager/vtkSMSession.cxx, line 288
Failed to automatically launch ‘pvserver’ for multi-core support. Defaulting to local session.
What is even more interesting, is that I tried ParaView 5.6.0, which worked in MPI until I had to close the application. For second run, it would never start again in MPI.
I have reverted to use pvserver and call with mpiexec provided in /Applications/ParaView/Contents/bin, however once I run ./mpiexec -n 8 ./pvserver --mpi (or without suffix --mpi), the terminal just hangs and doesn’t do anything.
Is anyone experiencing such issues? What could be the source of the problem?
