Now that I can load image (uniform rectilinear grid) data using the
Python Programmable Source, I'm trying to do this on four gpu nodes
(using mpirun -np 4 pvserver). Once I load my image, I thought it would
be automatically distributed (equally) to the four nodes, but coloring
by process id shows that everything happens on one node. What do I need
to do (short of writing out four pvti files and reading them back in) to
automatically distribute my data?
Thanks.

You probably need to update vtkImageExport and shallow copy its
output to the programmable source's output. You also need to add
something to the RequestInformation setting the whole extent. You
need something like:
from paraview import util
util.SetOutputWholeExtent(self, [0,nx-1,0,ny-1,0,nz-1])
By the way, there are better ways of getting numpy arrays into VTK
than the image import stuff. See some of the earlier blogs here:
Right. I found the RequestInformation info above from searching the
web. Then I was able to follow the instructions in the ParaView Guide
section 13.2.4 Reading binary 2D image. I basically replaced the image
import stuff with code analogous to the output assignment,
Thanks for your help.
