10.PP
11The following numbers
12are presented to suggest the scale of the Research
13.UX
14operation.
15Those of our users
16not involved in document preparation
17tend to use the system for
18program development, especially language work.
19There are few important
20``applications'' programs.
21.PP
22Overall, we have today:
23.PP
24.SP .5
25.TS
26center;
27r5 l.
28125	user population
2933	maximum simultaneous users
301,630	directories
3128,300	files
32301,700	512-byte secondary storage blocks used
33.TE
34.SP .5
35There is a ``background'' process that
36runs at the lowest possible priority; it is used
37to soak up any idle \*sCPU\*n time.
38It has been used to produce a million-digit
39approximation to the constant \fIe\fR,
40and other semi-infinite problems.
41Not counting this background work, we average daily:
42.SP .5
43.TS
44center;
45r 5 l.
4613,500	commands
479.6	\*sCPU\*n hours
48230	connect hours
4962	different users
50240	log-ins

55.PP
56The contributors to
57.UX
58are, in the traditional but here especially apposite
59phrase, too numerous to mention.
60Certainly, collective salutes are due to our colleagues in the
61Computing Science Research Center.
62R. H. Canaday contributed much to the basic design of the
63file system.
64We are particularly appreciative
65of the inventiveness,
66thoughtful criticism,
67and constant support of
68R. Morris, M. D. McIlroy,
69and J. F. Ossanna.
