Question: Consider the two matrix multiplication schemes in the table below. Assuming a fixed efficiency of E = 0.25, system B is more scalable than system A by the isoefficiency metric, for all values of b, c > 0. Assuming b = 4c, we have W(A) = 1.333 n1.5 and W(B) = n 1.5.

How much more scalable is B over A under the above conditions? See the parallel execution times in table below. Derive an expression for the ratio Tn(B) / Tn(A), when N > 2 sqrt (n).

Can system B be slower than system A? Explain why or why not.
