[Paraview] paraview and mpi

[Mattijs Janssens]

 From what I remember mpirun passes all info to other nodes via 
commandline arguments. It will add arguments like -p4pg (which gives the 
exact path of the executable per processor) when starting the other 
nodes which they then filter out. Add a few echo statements to mpirun (I 
think there is even a command line option to print some more info)

Could it be that Paraview expects LAM (which adds different commandline 
args)?

By the way we found LAM to be more reliable than mpich (we stopped using 
it at mpich1.2.4 so maybe it has improved)
