We have a very-heavily-loaded Vax here, and I am trying to figure out ways
of making it more usable, short of buying another one. One idea is to
rewrite the scheduler, so that time is allocated on a per-uid, instead of a
per-process basis. Has anybody done this to the kernel?

Henry in Bell Labs Technical Journal vol 63, october 1984, number 8, part2. when the BLTJ came out, there was much discussion of the price (originally outragously high, then lowered), and how to order a single copy from ATT, but i do not remember now. david -- david parter UWisc Systems Lab uucp: ...!{allegra,harvard,ihnp4,seismo, topaz}!uwvax!david arpa: david@rsch.wisc.edu

Henry in the last "UNIX System" issue of the the Bell Labs Technical Journal (vol 63. No.8 Part 2, October 1984). I suspect, however, that the scheduler described there is only available within Bell Labs. Paul Kleppner VenturCom, Inc. {harvard,mit-eddie}!cybvax0!vcvax1!venix
