- 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
- .TE

- 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.
