getScore
protected double getScore(double availableCpu, double availableMemory, TopologyDetails td)Get a score for the simulated user. This is used to sort the users, by their highest priority topology. The only requirement is that if the user is over their guarantees, or there are no available resources the returned score will be > 0. If they are under their guarantee it must be negative.- Parameters:
availableCpu- available CPU on the cluster.availableMemory- available memory on the cluster.td- the topology we are looking at.- Returns:
- the score.
