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 /Users/emonson/Programming/ParaView_git/ParaView/VTK/Parallel/vtkParallelRenderManager.cxx, line 1869 vtkIceTRenderManager (0x10b104a90): Failed to read window information Process id: 3 >> ERROR: In /Users/emonson/Programming/ParaView_git/ParaView/VTK/Parallel/vtkParallelRenderManager.cxx, line 1869 vtkIceTRenderManager (0x10be0ec40): Failed to read window information Process id: 1 >> ERROR: In /Users/emonson/Programming/ParaView_git/ParaView/VTK/Parallel/vtkParallelRenderManager.cxx, line 1869 vtkIceTRenderManager (0x10b604a10): Failed to read window information 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. :) -Eric ------------------------------------------------------ Eric E Monson Duke Visualization Technology Group On Aug 19, 2010, at 3:49 PM, Favre Jean wrote: > > i am having difficulty with pvbatch - compiled with Mesa 7.6 - running in > parallel and hanging after the first WriteImage in my python scripts. > > I have tested several compilations on different clusters, several MPI > (mvapich and openmpi) and still cannot make this work.
