[Paraview] Running Paraview on an SMP machine

[David Farrell]

Hi - I am new to the use of parallel visualization, and wanted to  
check it out a bit. I have several questions about using Paraview on  
an SMP (dual proc or otherwise) machine:

- When starting paraview in parallel - is the typical usage to start  
in client-server (so pvclient and pvrenderserver) mode with a  
multiprocess server or to start in distributed stand-alone mode  
(paraview)? Are there particular reasons to choose one over the other?

- The older online docs mention that if several processes share a  
display, the render windows may overlap and the resulting image may  
be corrupt. what is the typical way around this?

-  In goofing around, I tried adding the --use-offscreen-rendering  
flag to pvrenderserver, but still render windows appeared for the  
processes. Is this a sign that I don't have mesa installed or set up  
properly?

- In order to take advantage of the parallel rendering - would I need  
to feed decomposed data files into the program, or does it handle  
this internally? Also - Other than checking speedup in rendering, how  
can one check that the rendering is actually being done in parallel  
vs. duplicated on each process?


Thanks in advance,

Dave
