It is correct that MPI_Init is not called for builtin. This is because the paraview client application itself is not a parallel application. It has no MPI facilities, so MPI cannot be used within it. If you want to use MPI, you have to connect to a pvserver.

Hard time to locate the right code. When ParaView do not call MPI_Init this cause me some problem. My reader uses mpi io, and do not work without mpi. My 2 case is this: When ParaView not compile with MPI, reader not compile, so no one try to use it. No problem! When ParaView compile with MPI, reader works on all connection except built in. Problem! reader should work on all connection type + builtin. How can this be realise in the ParaView way?
