Multi-processing system study

The results are summarized of a multiprocessor systems design review. The systems were reviewed against use in a space station environment. The proposed designs were evaluated from a systems viewpoint in general and from the systems software in particular. The recommendations resulting from this evaluation are anticipated to be considered for the design of a multiprocessing system built around a SUMC. Two multiprocessing system designs were reviewed. The designs reviewed were highly functional and many questions could not be answered. However, several major issues were uncovered which could be evaluated to some detail, and which could greatly impact the SUMC-MP design. The major issues relevant to a multiprocessing system design revolve around the following functions: (1) Storage Management, (2) Processor Management, (3) Intermodule Communication, (4) Memory Access Interference, (5) System Efficiency, and (6) System Recovery/Reliability.
