Description: 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 A/D 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.  The resulting MUNIX system provides an effective mechanism for resource sharing in a laboratory environment and is the basis for protected real-time operation in a multi-user system. (Author)
