Detailed Description

Functions for packing the entries of a Tpetra::CrsMatrix for communication, in the case where it is valid to go to the KokkosSparse::CrsMatrix (local sparse matrix 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 matrix are "packed" (concatenated) in to a (view of) char* object in the following order:

1. number of entries (LocalOrdinal)
2. global column indices (GlobalOrdinal)
3. proces IDs (optional, int)
4. row values (Scalar)

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