4 | The following numbers | |
5 | are presented to suggest the scale of the Research | |
6 | .UX | |
7 | operation. | |
8 | Those of our users | |
9 | not involved in document preparation | |
10 | tend to use the system for | |
11 | program development, especially language work. | |
12 | There are few important | |
13 | ``applications'' programs. | |

15 | Overall, we have today: | |
16 | .PP | |
17 | .SP .5 | |
18 | .TS | |
19 | center; | |
20 | r5 l. | |
21 | 125 user population | |
22 | 33 maximum simultaneous users | |
23 | 1,630 directories | |
24 | 28,300 files | |
25 | 301,700 512-byte secondary storage blocks used | |
26 | .TE | |
27 | .SP .5 | |
28 | There is a ``background'' process that | |
29 | runs at the lowest possible priority; it is used | |
30 | to soak up any idle \*sCPU\*n time. | |
31 | It has been used to produce a million-digit | |
32 | approximation to the constant \fIe\fR, | |
33 | and other semi-infinite problems. | |
34 | Not counting this background work, we average daily: | |

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