[Paraview] inquiries on parallel pvserver nodes

I count 10 cores in the 192.168 domain. My suspicion is that MPI is having a problem when running with more than 10 processes and therefore having to run on nodes in both 192.168 and 202.185.
My advice is to first make sure that you can run any MPI job across all the nodes in your makeshift cluster. Do this using a test MPI program that is simpler than pvserver. Most MPI implementations come with a set of tests. If you can't find any on your system, there are many available for download; here is a good site: http://www.mcs.anl.gov/research/projects/mpi/mpi-test/tsuite.html
By the way, are you really running a program called pvclient? There has been no such executable since ParaView 2.6, which was released 2 years ago. If that is the case, I recommend updated to the latest version of ParaView.

am trying to utilize some desktops in our lab (say "lab A") to visualize some virtual heart.
on top of that, there are also some unused desktop from other lab ("lab B") which i plan to add in as the server.
below are my "hostfile" used during mpirun.
192.168.0.10 slots=4 max-slots=4
192.168.0.220 slots=2 max-slots=2
192.168.0.205 slots=2 max-slots=2
192.168.0.249 slots=2 max-slots=2
18.104.22.168 slots=2 max-slots=2
22.214.171.124 slots=2 max-slots=2
126.96.36.199 slots=2 max-slots=2
as we can see, the 192.168... series are from lab A and the 202.185.. series are from lab B.
the experiment started off fine as i'm also using a desktop from lab A (192.168.. series) to connect to the server.
when we reach np 11, the paraview (pvclient) fails to response when we try to establish a connection with the server.
are we missing out anything here?
appreciate all your response and answer in advance
