Abstract:

The design and implementation of MUNIX, a tightly-coupled symmetric multiprocessing PDP 11 based operating system providing real-time, interactive, and background processing facilities in a hierarchical memory environment is described. MUNIX is a variant of UNIX, an operating system for the PDP 11 developed at Bell Laboratories. The three major design goals of the system were 1 support for processes capable of real-time interaction with several dynamic graphics display units, an array processor, and a multi-channel AD converter 2 interactive and background processing facilities to support program development and, 3 management of the hierarchical storage created by the mix of shared and private memories of various speeds.
