[Paraview] ParaView & MPI Question(s)

[Troy Telford]

I hope this is a quick question:
What requirements are there for using ParaView with MPI?  (ie. MPI 2, etc)

I've been successful in compiling ParaView (and VTK) using a couple MPI 
implementations (Open MPI, for example), but not others, such as MVAPICH2.

Unfortunately, I don't get the luxury of saying "Use this MPI" to my users, so 
I'm mainly interested in eliminating MPI implementations which don't have the 
features required by ParaView.

Also -- I noticed that you can configure the command used to execute 'mpirun' 
using CMake.  (Things like the max number of nodes, etc).  Is the node count 
something that is determined only at compile time, or is it configurable 
afterwards?
