Abstract:

This report describes executives built using the Operational Software Concept OSC. These executives are designed to operate on a federated network of four DAIS processors connected by DAIS multiplex data busses. In fact, the executives and applications, represented by stubs, have been implemented on a two processor system. The applications supported by the executives are specified using Directed Flowgraphs DFG as described in AD-A010 415. This report is divided into three sections and an Appendix. The first section describes the process of building an executive based on a DFG. The second section describes the parameters affecting system performance that are associated with the DFG supported by the executives. The third section presents the baseline executive statistics, tuning method descriptions and statistics for the final tuned executive. The Appendix provides program listings of intermediate tuning results of the final tuned executives.
