[5] < §1.8> when a program is adapted to run on multiple processors in a multiprocessor system, the execution time on each processor is comprised of computing time and the overhead time required for locked critical sections and/or to send data from one processor to another. assume a program requires t = 100 s of execution time on one processor. when run p processors, each processor requires t/p s, as well as an additional 4 s of overhead, irrespective of the number of processors. compute the per-processor execution time for 2, 4, 8, 16, 32, 64, and 128 processors. for each case, list the corresponding speedup relative to a single processor and the ratio between actual speedup versus ideal speedup (speedup if there was no overhead).
