  11. The following numbers
  12. are presented to suggest the scale of the Research
  13. .UX
  14. operation.
  15. Those of our users
  16. not involved in document preparation
  17. tend to use the system for
  18. program development, especially language work.
  19. There are few important
  20. ``applications'' programs.
  21. .PP
  22. Overall, we have today:
  23. .PP
  24. .SP .5
  25. .TS
  26. center;
  27. r5 l.
  28. 125 user population
  29. 33 maximum simultaneous users
  30. 1,630 directories
  31. 28,300 files
  32. 301,700 512-byte secondary storage blocks used
  33. .TE
  34. .SP .5
  35. There is a ``background'' process that
  36. runs at the lowest possible priority; it is used
  37. to soak up any idle \*sCPU\*n time.
  38. It has been used to produce a million-digit
  39. approximation to the constant \fIe\fR,
  40. and other semi-infinite problems.
  41. Not counting this background work, we average daily:
  42. .SP .5
  43. .TS
  44. center;
  45. r 5 l.
  46. 13,500 commands
  47. 9.6 \*sCPU\*n hours
  48. 230 connect hours
  49. 62 different users
  50. 240 log-ins

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