For a problem size of interest, 6 percent of the operations of a parallel program are inside I/O functions that are executed on a single processor.
What is the minimum number of processors needed in order for the parallel program to exhibit a speedup of 10? (Hint: using Amdahl’s law.)

A1-megabit computer memory chip contains many 27 ff capacitors. each capacitor has a plate area of 3.09 × 10−11 m 2 . determine the plate separation of such a capacitor (assume an empty parallel-plate configuration). the characteristic atomic diameter is 10−10 m = 1 ˚a, and the permittivity of a vacuum is 8.8542 × 10−12 c 2 /n · m2 . answer in units of ˚a.
