[TUHS] UNIX on (not quite bare) System/370

[Marc Donner]

There was a track of USENIX 1986 called "UNIX on Big Iron."  Peter Capek of
IBM was the chair and Gene Miya and Jim Lipkis rounded out the program
committee.  The proceedings are available.

   - User Requirements for Future-nix - Gene Miya
   - Experience with Large Applications on UNIX - Bob Bilyeu
   - UNIX Scheduling for Large Systems - Jeffrey Straathof, Ashok Thareja,
   Ashok Agrawal
   - A Straightforward Implementation of a 4.2BSD on a High Performance
   Multiprocessor - Dave Probert
   - Porting UNIX to the System/370 Extended Architecture - Joseph R Eykholt
   - Full Duplex Support for Mainframes - Don Sterk
   - Concentrix -- A UNIX for the Alliant Multiprocessor - Jack Test
   - A User-Tunable Multiprocessor Schedule - Herb Jacobs
   - Considerations for Massively Parallel UNIX Systems on the NYU
   Ultracomputer and the IBM RP3 - Jan Edler, Alan Jottlieb, Jim Lipkis
   - UNIX of CTSS for the Cray-1, Cray X-MP, and Cray-2 Supercomputers -
