Is a program that obtains linear speedup strongly scalable? Explain your answer.

Bob has a program that he wants to time with two sets of data, input data1

and input data2. To get some idea of what to expect before adding timing

functions to the code he’s interested in, he runs the program with two sets of

data and the Unix shell command time:

$ time ./bobs prog <>

real 0m0.001s

user 0m0.001s

sys 0m0.000s

$ time ./bobs prog <>

real 1m1.234s

user 1m0.001s

sys 0m0.111s

The timer function Bob is using has millisecond resolution. Should Bob use

it to time his program with the first set of data? What about the second set of

data? Why or why not?
