### 16.1.6. User Specified Direction

The simplest partitioning algorithm is coordinate based in a direction whose vector components can be specified directly. This partitioning method uses the most efficient algorithm, and also has small additional memory overhead.

The partitioning process itself is partially controllable through the direction specification. However, in general, larger overlap regions occur compared with both the MeTiS and recursive coordinate bisection partitioners. This application is generally recommended only for special geometries.
