Hello,
To write such files, ParaView uses the VTK class vtkHoudiniPolyDataWriter which produces files according the following specification: http://www.sidefx.com/docs/houdini15.0/io/formats/geo
Clearly, this file format is not a parallel file format and so the writer. Then it’s a default behavior of ParaView to reduce data to rank 0 before writing for non-parallel file formats.
That said, it could be possible quite easily to use a Programmable Filter that would pass the dataset to an instance of the Houdini writer with a formatted filename with processor rank.
Hope this helps,
Best,
Joachim
