A Real-Time Multiprocessor Simulator (RTMPS) has been developed at NASA Lewis Research Center. The RTMPS uses parallel microprocessors to achieve computing speeds needed for real-time engine simulation. This report describes the use of the RTMPS system to simulate a small turboshaft engine. The process of programming the engine equations and distributing them over one, two, and four processors is discussed. Steady-state and transient results from the RTMPS simulation are compared with results from a main-frame-based simulation. Processor execution times and the associated execution time savings for the two and four processor cases are presented using actual data obtained from the RTMPS system. Included is a discussion of why the minimum achievable calculation time for the turboshaft engine model was attained using four processors. Finally, future enhancements to the RTMPS system are discussed including the development of a generalized partitioning algorithm to automatically distribute the system equations among the processors in optimum fashion.

It is certain, that from our Saviour's time to the present, there have ever been persons whose dispositions and lives have been formed by the rules of the New Testament; men who have been real, not merely nominal Christians, who believed the doctrines of the gospel, loved them because of their divine excellency, and suffered gladly the loss of all things, that they might win Christ, and be found in him. It is the history of these men which I propose to write. It is of no consequence with respect to my plan, nor of much importance I believe in its own nature, to what external church they belonged. I intend not to enter with any nicety into an account of their rites and ceremonies, or forms of church government, much less into their secular history. Even religious controversies shall be omitted, except those which seem to bear a relation to the essence of Christ's religion, and of which the history of his real church seems to require some account. Let not the reader expect, that the actions of great men (great in a secular view I mean) will be exhibited to his notice. Nothing but what belongs to Christ's kingdom shall be admitted, and genuine piety is that alone which I intend to celebrate. - Summary by Introduction
