PURDUE did a multiprocessor UNIX by replacing the SBI terminator in
their VAX 780 with another CPU. The master processor handles most
of the kernel with time left over for user processes and user processes
are run in the slave CPU. Gould uses most of the same code to run their
dual processor Powernode systems (as a matter of fact, Gould sucked up
a lot of the Purdue talent to do it).
Doing the Master/Slaves approach is a fairly old idea. It was first
published in a paper from the Navy Postgraduate School in 1975. I don't
have the reference.
