Unix as an Application Program

Category: Desktops, Laptops and OS, Servers and Server OS

Overview Off late the author has had running at CMU a computing environment in which the functions of a traditional Unix system are cleanly divided into two parts: facilities which manage the hardware resources of a computer system (such as CPU, I/O and memory) and support for higher-level resource abstractions used in the building of application programs, e.g. files and sockets. This paper describes the implementation of Unix as a multithreaded application program running on the Mach kernel. The rationale, design, implementation history and performance of the system is presented.
