ParaView/ParaView Readers and Parallel Data Distribution

Under Development

File Extension	Format Description	Reader	Parallelism	Time
*.vtk	Legacy VTK Files	Legacy VTK reader	This file format has no support for saving parallel distribution of data. Hence ParaView does the following: Structured Data For structured data, this reader reads the entire file on all processes and then crops the structured extents on each process so that for each process, the filters downstream process a block of the structured data alone. Unstructured Data The root node reads the entire file and then the data is distributed to all processes (using MPI) after an internal, fairly naive, partitioning algorithm (vtkTransmitUnstructuredGridPiece or vtkTransmitPolyDataPiece).	Time supported only as a file series.
