Hey Jean,
I am getting the same behavior on my Mac OS X 10.6 compiled with OpenMPI (but
no OSMesa). I can run scripts like yours from the ParaView Python shell when
connected to a four-process pvserver just fine, and it works from the same
build of pvbatch run in serial (without mpirun), but when I try to run pvbatch
with
mpirun -np 4 ./pvbatch coloredSphere.0.py
it hangs after writing the first image and giving me this output:
vtkSphereSource : [ ...........]
vtkSphereSource(3) : [ ...........]
vtkSphereSource(1) : [ ...........]
vtkSphereSource(2) : [ ...........]
vtkPVGeometryFilter : [ ...........]
vtkPVGeometryFilter(1) : [ ...........]
vtkPainterPolyDataMapper : [ ...........]
vtkPainterPolyDataMapper : [ ...........]
Process id: 2 >> ERROR: In

Even a simple example like this hangs in the same way:
from paraview.simple import *
view = CreateRenderView()
sphere = Sphere()
Show()
Render()
WriteImage("sphere.0.png")
WriteImage("sphere.1.png")
Sorry I don't have any solution, but hopefully this will help someone who knows
more figure it out. :)
