Please explain the concept and show all steps. Thank You!

1) Let's assume that only the compute is parallelizable and the ideal speedup of it is N, which is the number of processors. What is the overall speedup with N processors? (5 points) 2) Let's assume that both the compute and disk I/O is parallelizable. The ideal speedup of compute is N, i.e., the number of processors. However, as we increase N, the disk I/O performance will maintain the same speedup if N is no greater than M, and drops P percent every time a new processor is added beyond M( i.e., >M ). What is the overall speedup with N processors? ( 10 points)
