object ProcessCoordinate

ProcessCoordinate exposes a mechanism that allows a process to be furnished with a coordinate between [0.0, 1.0). The coordinate is calculated relative to other nodes in the process' peer group such that each coordinate is uniformly spaced from another. The result is that each process that is part of the respective group is now part of a topology with a sense of order and proximity.
