A parallel program runs for 2000 seconds on 128 processors. After careful investigation, we found that only 5 seconds out of the 2000 seconds were actually spent in redundant operations, and the rest of the code was fully parallelized. (a) What's the “scaled” speedup of this program? (b) What is the efficiency of the program on 128 processors? (c) What would be the sequential run time of this program?
