Detailed Description

This partitioner is intended only for internal use in IBAMR (e.g., to generate platform-independent partitionings of meshes). It differs from libMesh::CentroidPartitioner in a few significant ways:

1. Centroids are sorted lexically instead of by a specified coordinate.
2. To improve stability the least significant bits are cleared by casting the coordinates to and from single precision.
3. To improve stability a stable sorting algorithm is used.
