Hi. I do "mpirun -np 4 pvserver --client-host=xxx --use-offscreen-rendering", and connect a ParaView client viewer. I can see 4 nodes in the memory inspector, but when I start a python shell in ParaView, and do:

from mpi4py import MPI
print MPI.COMM_WORLD.Get_size()

I get the answer 1. Shouldn't it be 4? Thanks.
