Hi,<div><br></div><div>I've got a few questions about the python example, CoProcessingExample.py. First, FYI, when downloaded to my mac the script contains indentation errors so python can't parse it. Don't know what is going on (maybe our firewall is trying to prevent us from using python by messing up the indentation!). Second, my interepreter couldn't find the mpi module even though my PYTHONPATH etc were set up as on the wiki. I use mpi4py to manipulate mpi anyway, so I just modified the script to use it instead. Will that be OK in general or do I need to track down the mpi module in order for the coprocessing library to work correctly?</div>
<div><br></div><div>In terms of using the example, I constructed an image source in paraview and colored it with the pointData, then saved the state script. I had to get some of the name strings straightened out but the example appeared to run and generated a sequence of png files. Does anybody have a simpler state/coprocessing script for that example that I can use for learning purposes? The next thing to do is expose my solver's vtk data structures to the co-processor and generate a coprocessing script for it. I'm afraid given my weak understanding of what is going on, generating the state script from one of my xdmf data sets and trying to get it to work inside the coprocessing is going to be difficult (our i/o and existing vtk visualization are completely independent). It might be easier if I new how to wrote the state script by hand to execute something very simple. I've got lots of vtk pipelines set up for the data under our current approach to runtime vtk viz so I was hoping I could just paste in something similar into the state script.</div>
