Detailed Description

assigner for use with DIY

vtkDIYExplicitAssigner is a diy::StaticAssigner specialization that be used where the block assignment is not strictly round-robin or contiguous which assumes blocks equally split among ranks. This supports the case where each rank has arbitrary number of blocks per rank. The constructor is provided the mpi communicator and the number of local blocks. It performs parallel communication to exchange information about blocks with all participating ranks.

vtkDIYExplicitAssigner also supports ability to pad each rank such that the total number of blocks across all ranks is a power of two.
