XML partitioned-dataset writer does not work in parallel correctly.
- Connect to pvserver (2 ranks) using ParaView
- Open can.ex2, apply
Adaptive Resample to Imagefilter, Apply.
- Show as
Surfaceand color by
vtkProcessIdto confirm there are as many blocks as ranks (2 in this case)
- Save data as
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.
