[Paraview] how to run ParaView 3.4.0 on MacOS Leopard in parallel?

[Karen Lee]

Hi, thanks for all of your responses.  It looks like the ParaView Guide book
is out-of-date, as it tells you that the client can be launched directly
with "mpirun -np <xx> paraview" as an alternative to running pvserver
separately.

Now that we are using pvserver, it is partially working.

We installed pvserver (in /usr/local/bin), and then used the "Connect"
option in the File menu to connect to a server running on "localhost" (Add
Server, then specifying Client/Server connecting to localhost port 11111,
launching pvserver with "/usr/bin/mpirun -np 7 /usr/local/bin/pvserver"),
and connected to the server successfully.

Unfortunately, using pvserver on the same (8-processor) machine seems to be
significantly slower and more buggy than running the client by itself (we
tried -np 7, and also -np 2), for a fairly large (million-point)
unstructured-grid dataset that takes about 20 seconds for volume rendering
with one processor.  We had thought that this problem would be big enough to
benefit from at least using a couple of CPUs.

When we connect to pvserver on the same machine, it not only takes much
longer to render (regardless of the number of CPUs we launch pvserver on),
but there are also some weird screen artifacts where it seems to open up a
second rendering window (with no controls or window decorations, just a
square with a duplicate of the rendering contents) that we cannot get rid
of.  At that point the program freezes.

Any suggestions?  We are using the precompiled paraview 3.4.0 from the
paraview web site, compiled for MacOS Leopard/Intel, running on an 8-cpu
MacPro with 16GB of RAM.

Thanks,
Karen Lee
