Graph

These algorithms provide generic graph coloring capabilities used by Gauss-Seidel, multigrid aggregation, etc... We distinguish to main categories of algorithms, distance 1 coloring and distance 2 coloring. We also provide a coloring handle that allows users to easily control the behavior of the algorithms.

Graph coloring handle

The graph coloring handle is extending the KokkosKernels handle to provide options that are specific to coloring algorithms.

Distance 1 graph coloring

Distance 1 coloring algorithms will ensure that each node and its neighbors have different colors.

Distance 2 graph coloring

Distance 2 coloring algorithms will ensure that each node, its neighbors and its neighbors' nightbors have different colors.

You can’t perform that action at this time.
