One possibility for increasing available computational power
at resonable cost is to construct multiprocessors out of the
new generation of powerful microprocessors.  This  presenta-
tion  describes a multiprocessor version of the Tunis opera-
tion system that is designed  to  run  on  several  tightly-
coupled  microprocessors.  In this system each processor has
its own copy of the operating system in local  memory  which
it  may  concurrently execute. Global memory is used only to
hold system wide data such as open file tables. The  result-
ing  reduction  in  required interprocessor bandwidth allows
the system to maintain throughput without necessitating  on-
board caches or specialized busses.
