17.1.3. Recursive Coordinate Bisection

The Recursive Coordinate Bisection partitioning algorithm is very efficient with respect to CPU time and additional memory. The partitioning is based on the global coordinates of the mesh. Each step of the recursive bisection is performed in the coordinate direction with the largest dimension.

Recursive Coordinate Bisection

Like MeTiS, the Recursive Coordinate Bisection partitioner uses a fast, fully automatic algorithm, but it has only a small additional memory overhead. A particular disadvantage is that larger overlap regions can exist compared with the MeTiS partitioner, and each partition may contain separate parts.
