Amdahl's law gives limits on the maximum possible speedup of programs. What is the maximum possible speedup of the following programs: 1, 10% sequential, 90% parallel, with processors used. 2.90% sequential, 10% parallel, with 32 processors used. 3. 5% sequential, 95% parallel, with an unlimited number of processors Discuss some reasons why the maximum theoretical speedup is not often achieved in computations
