10 pages of text: shared
1 page of data: unshared x 100 = 100
pages.
Shell: 10 pages of text, 1 page of data.
20 pages of shared text.
2 pages of data x 100 = 200 pages.
Editor
10 pages of shared text
4 pages of data x 100 = 400
Compiler
1 page of unshared text.
= 300 pages
2 pages of unshared data
Assignment
Problem 2
No thrashing means that we have the pages
for the problem at hand available.
shell text, editor text, and one of compiler
or assignment text: 40 pages of read-only
text.
data for shell and editor: 300 pages
data for one of compiler or run: 400 pages
Need:
This is an upper bound; it is likely that people
will be doing different things and that whole
sections of the shell, editor, and/or compiler
will be swapped out.
