<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>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. <BR>
<BR>
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: <a href="http://www.mcs.anl.gov/research/projects/mpi/mpi-test/tsuite.html">http://www.mcs.anl.gov/research/projects/mpi/mpi-test/tsuite.html</a><BR>
<BR>
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.<BR>

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