public abstract class AbstractProrater
extends OperationMapper

A Prorater is a simple kind of a load balancer aiming to maximize a homogeneous load by prorating the activities among computing nodes. The priority property of the activities is the dominant criterium for prorating. Nodes with a quality below resource.prorater.min_quality are skiped until its quality grows. The quality (in [0,1]) is a monotone reciprocal function of the load.
