Issue created Sep 07, 2020 by Utkarsh Ayachit@utkarsh.ayachit⛰Contributor

XML partitioned-dataset writer does not work in parallel correctly.

  • Connect to pvserver (2 ranks) using ParaView
  • Open can.ex2, apply
  • Create Adaptive Resample to Image filter, Apply.
  • Show as Surface and color by vtkProcessId to confirm there are as many blocks as ranks (2 in this case)
  • Save data as foo.vtpd

Now restart ParaView (as builtin) and load the file that was saved. Either it will fail to load correctly or will only have 1 block. This is a bug.

This is happening because the writer for vtkPartitionedDataSet is not parallel aware and each rank ends up overwriting what an other rank wrote.

Same is probably true for vtkPartitionedDataSetCollection.
