I am taking a parallel programming class and am really struggling with understanding some of the computational complexity calculations and algebraic simplifications.Specifically for the bitonic sort algorithm I am looking when each processor is given a block of elements.

I am looking at situations when either a hypercube or 2D mesh interconnection network is used. I am given the following definitions for the calculation of Speedup, Efficiency, Iso-Efficiency and determining if the solution is cost optimal. I can understand how Speedup is determined but am totally lost as to how to solve for Efficiency and Iso-Efficiency. I think I understand cost-optimality as well. Given below are the equations.
