IX. STATISTICS
PP
The following numbers
are presented to suggest the scale of the Research
UX
operation.
Those of our users
not involved in document preparation
tend to use the system for
program development, especially language work.
There are few important
``applications'' programs.
PP
Overall, we have today:
PP
SP .5
TS
center;
r5 l.
125 user population
33 maximum simultaneous users
1,630 directories
28,300 files
301,700 512-byte secondary storage blocks used
TE
SP .5
There is a ``background'' process that
runs at the lowest possible priority; it is used
to soak up any idle \*sCPU\*n time.
It has been used to produce a million-digit
approximation to the constant \fIe\fR,
and other semi-infinite problems.
Not counting this background work, we average daily:
SP .5
TS
center;
r 5 l.
13,500 commands
9.6 \*sCPU\*n hours
230 connect hours
62 different users
240 log-ins

X. ACKNOWLEDGMENTS
PP
The contributors to
UX
are, in the traditional but here especially apposite
phrase, too numerous to mention.
Certainly, collective salutes are due to our colleagues in the
Computing Science Research Center.
R. H. Canaday contributed much to the basic design of the
file system.
We are particularly appreciative
of the inventiveness,
thoughtful criticism,
and constant support of
R. Morris, M. D. McIlroy,
and J. F. Ossanna.
