Detailed Description

Declaration of functions for unpacking the entries of a Tpetra::CrsGraph for communication, in the case where it is valid to go to the KokkosSparse::CrsGraph (local sparse graph data structure) directly.

Warning

This file, and its contents, are implementation details of Tpetra. The file itself or its contents may disappear or change at any time.

Data (bytes) describing the row of the CRS graph are "packed" (concatenated) in to a (view of) packet_type* object in the following order:

1. global column indices (GO)
2. process IDs (optional, int)

The functions in this file are companions to Tpetra_Details_packCrsGraph.hpp, i.e., Tpetra_Details_packCrsGraph.hpp implements the packing order described above to ensure proper unpacking.
