More information on SSS can be found on ftp.chorus.fr, look among their
index for references to implementing Chorus on the ipsc/386 and the
T9000, and on loosely coupled multiprocessors. The papers are:
UNIX on a Loosely Coupled Architecture: The Chorus/MiX Approach
(CS/TR-91-49)
Chorus/MiX, A Distributed UNIX, on Multicomputers
(CS/TR-92-10)
Andy "what have we learnt" Tanenbaum has also done work in this area
with the Amoeba Operating system (I don't have the papers handy, but here
is a reference)
Tannenbaum - Andrew Tanenbaum, Rob van Renese, and Hans van
Staveren. {\it A Retrospective and Evaluation of the Amoeba Distributed
Operating System}, Techical Report, Vrije University, Amsterdam, October,
1989, pp. 27.
Another good paper is:
Hildebrand - Dan Hildebrand. {\it An Architectural Overview of
QNX.} The proceedings of the Usenix Workshop on Micro--Kernels \& Other
Kernel Architectures, Seattle, April, 1992.
This, and some amoeba papers, are also available for anon ftp on
ftp.cse.ucsc.edu under pub/qnx and pub/amoeba.
More info can by found by doing an archie search on amoeba.
Basically all it boils down to is (a gross oversimplification) making
loosely coupled non shared memory processors (possibly several single
board computers in a VME chassis) feel like a single computer. This does
seem to be a good way to go, shared memory multiprocessors tend to run
out of memory to processor bandwidth. I am not sure if Plan 9 can do
SSS, perhaps someone can correct me if I am wrong.
