Mark, By the way, we might be able to answer your question better if you gave extra information about what you are trying to do. Short of writing a book on the ins and outs of parallel processing in ParaView, we can only guess what you might need.
Most filters, even though they are run in parallel only need to consider the local partition of data they are given. There are, of course, exceptions, but if you give us some hints at what you are trying to do we might be able to give you better advice. -Ken From: David E DeMarle <[email protected]<mailto:[email protected]>> Date: Thursday, March 27, 2014 9:21 AM To: "Vanmoer, Mark W" <[email protected]<mailto:[email protected]>> Cc: paraview <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] Re: [Paraview] parallel filter question Pretty much yeah. ParaView does interprocess communication as little as it can. Grep for vtkMPIController in ParaViewCore/VTKExtensions and VTK/Filters/Parallel for examples of the mechanics of having parallel filters communicate amongst themselves. David E DeMarle Kitware, Inc.

I was re-reading section 13.4 of the ParaView Guide and wanted to clarify, is it correct to say that ParaView only does gathering for the image output that IceT is going to composite? That for filters that need to use any other data from the pipeline for non-image output, that gathering has to be done by hand?
