The multithreaded algorithm works by atomically assigning each face's group ID to the surrounding edges. If the ID for the edge is different than one set previously, the edge becomes a boundary. Using the edge to face topology map was also tested, but it wasn't faster, and given the large memory usage of the map, the increased complexity of this algorithm was considered worthwhile.
