To counter the pessimism of Amdahl, Quinn introduces Gustafson’s Law. $$ S(n) = n - (1-n)(1-f) $$ Instead of keeping the problem size fixed and adding processors, Gustafson suggests keeping the time fixed and increasing the problem size. Quinn’s Analysis: This is the theoretical justification for supercomputing. As we add processors, we should solve larger problems, not just solve the same problem faster. This makes high parallel efficiency achievable.
