# MATCOLORINGJP
Parallel Jones-Plassmann coloring 


## Options Database Key

- ***-mat_coloring_jp_local -*** perform a local coloring before applying the parallel algorithm



## Notes
This method uses a parallel Luby-style coloring with weights to choose an independent set of processor
boundary vertices at each stage that may be assigned colors independently.

Supports both distance one and distance two colorings.
