Application of Parallel Processing to Real Time Flight Simulation Using the OCCAM Language

摘要

A simulation of the longitudinal motion of a Boeing 747 aircraft was designed using the programming OCCAM. A parallel processing structure was constructed. A 2 x 2 square array of transputer microprocessors is used, although the results are applicable to larger arrays of processors. A generalized communication system linking the processors in the array was formulated in OCCAM. It allows simulation models to be split up into separate parallel components with the minimum consideration for data transfer and sequencing between the concurrent elements. Time response results show the dynamic model to be working successfully. The study was completed on a multiuser VAX11/780 which sequentially schedules the separate designated parallel processes. As a result the simulations were not executed in real time, although the application of the work is to real time systems.
