hey guys,

i'm looking at summer 2000 final on HKN
(http://hkn.eecs.berkeley.edu/student/online/cs/61C/2000/su-f.pdf) and
i'm wondering for question 4, how did they figure out the set assoc and
replacement policy? i didn't really understand this lab too well- i can
see where they get the other parameters, but the last 2 are lost on me

The short answer is that it's just a matter of examining the expected
hit-to-miss ratios, and realizing how that will change the times.

The long answer is too long to discuss using the newsgroup. It's really
something that needs to shown in office hours (or a review session),
using diagrams.
