Abstract
An open operating system, which provides a high degree of
programming flexibility and efficiency, generally requires that all
programs be written in a single language and provides no protection
other than that which is available from the compiler. It is noted that
these limitations become unacceptable on a workstation that must run
untrusted software written in many different languages. Psyche, an open
operating system designed to make the most effective possible use of
shared-memory multiprocessors and uniprocessor machines, is presented.
It combines the flexibility of an open operating system with the ability
to write in multiple languages and to establish solid protection
boundaries. It also provides the efficiency of an open operating system
for programs that do not require protection
