Interface Pfqn_busyp.RateFunction

Enclosing class:
Pfqn_busyp
public static interface Pfqn_busyp.RateFunction
The load-dependent rate of one node, as a FUNCTION of the jobs it holds. A DENSE TABLE CANNOT EXPRESS AN INFINITE SERVER. The open-network form below truncates its tail adaptively and may need the rate at an order far beyond any table a caller would build, and the Matrix overloads answer such a query with their last column -- correct for the multiserver staircase, which saturates at c/S, and wrong for a delay station, whose rate is k/S and grows without bound. The MATLAB and C++ ports of this routine have always taken a function for that reason; this is its Java spelling, and the Matrix overloads are now a wrapper over it.

    • rate

      double rate(int node, int jobs)
      Parameters:
      node - zero-based node index in the ORIGINAL numbering handed to pfqn_busyp, not the subnetwork's
      jobs - number of jobs held, 1 or more
      Returns:
      the total service rate of the node at that occupancy
