This problem studies the effect of changing page sizes in a demand paging
system. The following sequence of requests for program words is taken from a
460-word program: 10, 11, 104, 170, 73, 309, 185,245,246,434,458, and
364. Main memory can hold a total of 200 words for this program, and the
page frame size will match the size of the pages into which the program has
been divided.
Calculate the page numbers according to the page size; divide by the page size,
and the quotient gives the page number. The number of page frames in memory
is the total number, 200, divided by the page size. For example, in problem (a)
the page size is 100, which means that requests 10 and 11 are on Page 0, and
requests 104 and 170 are on Page 1. Therefore, the number of page frames is
two.
a.) Find the success frequency for the request list using a FIFO replacement
Algorithm and a page size of 100 words (there are two page frames).
b.) Find the success frequency for the request list using a FIFO replacement
Algorithm and a page size of 20 words (10 pages, 0 through 9).
c.) Find the success frequency for the request list using a FIFO replacement
Algorithm and a page size of 200 words.
d.) What do your results indicator ''Can you make any general statements about
what happens when page sizes are halved or doubled?
e.) Are there any overriding advantages in using smaller pages? What are the
offsetting factors? Remember that transferring 200 words of information
takes less than twice as long as transferring 100 words because of the
way secondary storage devices operate (the transfer rate is higher than the
access, or search/find, rate).
f.) Repeat (a) through (c) above, using a main memory of 400 words. The size
of each page frame will again correspond to the size of the page.
g.) What happened when more memory was given to the program? Can you
make some general statements about this occurrence? What changes might
you expect to see if the request list was much longer, as it would be in real life?
.
h.) Could this request list happen during the execution of a real program?
Explain.
i.) Would you expect the success rate of an actual program under similar
conditions to be higher or lower than the one in this problem?
