XBC-XBC Link Load Equation
A simple calculation can be made to evaluate whether or not a particular configuration will have bottlenecks.
1. The number of cells on one quad, Qx, that talk to another quad Qy
2. The total number of cells is Qt
3. The number of links between the two quads is L. (Always 1)
4. Link load is Qx*Qy/Qt/L. (Link load = 4*4/8/2 = 1).
