Yes and no. If you compiled paraview without MPI, then it will have
compiled hdf5 (see thirparty dir in source tree) using serial HDF5, so you
are linking to hdf5 with no parallel support.

If you compile paraview and set VTK_USE_SYSTEM_HDF5 to ON then you can
link to a parallel hdf5 that you supply and can do what you like, but
you’ll probably need to do mpi_init etc from inside your plugin as
paraview will not have done it for you.
