Question

In its simplest form, Amdahl’s Law maintains that if a given program would take one hour to run to completion with one processor, but 80 percent of the program had to run sequentially (and therefore could not be sped up by applying additional processors to it), then a resulting parallel program would run only a maximum of ____ percent faster.

Answer 1

Answer:

The correct answer is 20.

Explanation:

Amdahl's Law is named for the computer architect Gene Amdahl, it is used to find out the maximum improvement of a system when only a part of it is improved. It states that: The improvement obtained in the performance of a system due to the alteration of one of its components is limited by the fraction of time that component is used. The speed increase of a program using multiple processors in distributed computing is limited by the sequential fraction of the program
