Problem 3:

  1. Amdahl's Law is as applicable to software as it is to hardware. An oft-cited programming truism states that a program spends 90% of its time executing 10% of its code. Thus, tuning a small amount of program code can often time have an enormous effect on the overall performance of a software product. Determine the overall system speedup if:
    1. 90% of a program is made to run 10 times as fast (900% faster).

Answer #1

a. Given, The fraction enhanced F = 0.9

  The speedup of the enhanced fraction S = 10 times

Overall Speedup =>

=>

=> 5.26

Therefore, the overall speedup = 5.26

    IT's About Business 4.1 The Heartbleed Bug What Is Heartbleed? OpenSSL, an open-source software package, is a popular type of transport layer security (TLS) software (discussed later in this chapter) that secures numerous websites around the world. Web servers use OpenSSL to encrypt sites. Such sites show up in browsers with a “lock” icon and the “https” prefix in the address bar. The encryption protects Internet sites offering banking, shopping, email, and other private communications. Roughly two out of three...
