Great Punf NF) VY UNIX NEWS PAGE 4 MUNIX - A Multiprocessor UNIX Be. E. Allen and G. tL. Barksdale, Jr. Computer Science Group Naval Postgraduate School Monterey, California 93940 The Naval Postgraduate School Signal Processing and Display Laboratory is a -university laboratory engaged in research efforts in computer graphics, signal processina, operating systemsSs and hybrid computing. The laboratory is used for student instruction as well as for student and faculty research. . The confiquration of the Signal Processing and Display Laboratory iS shown in Figure 1. The system can be viewed as a three bus ensemble, with the respective functions of data acquisitions signal processing, and display. When bus cycles are not required by real-time processes, the data acquisition and display busses support program development activities. The display system includes a 256K word fixed head disk, a Ramtek color displays a Tektronix 4014 display with enhanced araphicsr 3a Vector General 30D system, a Hughes Conographic console, a data tablet, a Versatek printer/plotters and an EPC graphic recorder. Peripherals for the Data Acquisition controller inctude both large (96M words) and small (2.5M words) disk systemsr magnetic tapes, * a@ocard readers a line printery and a sixteen line programm=- able terminal multiplexer. Dual ported core memory (88K words) is accessible from either UNIBUS. The signal pro- cessing subsystem consists of a CSP 125 controller with 4K words of 125 nanosecond memory, an array processor, and “tiie -{- ot PAGE 5 16K word banks of three ported memory. UNIX compatible dev= ice drivers have been developed for each of these perj-= pherals. To control this diverse hardware suite, we have evolved MUNIX? a tightly-coupled symmetric multiprocessor version of UNIX. <A single copy of the system residing in shared memory is executed by both = processors independently. P and V operators are used for synchronization. In order to provide the increased address space necessary to support the mul- tiprocessor system, UNIX was modified to seperate kernel I and D space. In support of the signal acquisition researcher a@ new process classificationr real-time, has been added. When a process is granted real-time statuses it is locked in memorye aiven the highest priority possible, and preemptive- ly allocated a processor whenever it comes ready. Other comoleted work includes the development of a dynamic symbolic debugging tool having breakpoint capabili- ty, a rather basic PDP 11 virtual machine monitor which exe~ cutes under MUNIX, several on-line diagnostic packages, a Vine editor which facilitates correction of typing mistakes, system catis which gracefully stop or bootstrap the system, and enhancements to the text editor, the text orocessor, the C compiter, and the loader. Work presently underway in-- ctudes a performance measurement subsytems several) adaptive schedulers, a demand paged memory manager? and a hardened file system.
