StaticCrsGraph

The StaticCrsGraph is a Compressed row storage array with the row map, the column indices and the non-zero entries stored in 3 different Kokkos::Views. Appropriate types and functions are provided to simplify manipulation and access to CRS data on either a host or device.

Usage:

using StaticCrsGraphType = Kokkos::StaticCrsGraph<unsigned, Space, void, void, unsigned>;
StaticCrsGraphType graph();

const int begin = graph.row_map[0];
const int end = graph.row_map[1];

double sum = 0;
for (int i = begin; i < end; i++) {
  Kokkos::View<unsigned, Space> v(graph.entries(i));
  for (int j = 0; j < v.extent(0); j++) {
     sum += v(j);
  }
}
