Applications are often times categorized as either computation bound or I/O bound. The former spends most of its execution time on computation, while the latter spends most of its time waiting for I/O (i.e. disk, network access, etc.). Use Amdahls Law to answer the following questions:

(a) Suppose you have an application that spends 65% of its time waiting for disk access and 35% of its time on computation. Is this system I/O bound or computation bound?

(b) If you were to run this application on a processor that is 25x faster but with the same I/O speed, what would be the potential speedup? 1

(c) If instead, you ran the application on a system with the same processor speed but a disk that is 2.5x faster, what would be the potential speedup?

(d) Describe how you might go about improving the disk access of this system.
