Development, Analysis, and Verification of a Parallel Hybrid Dataflow Computer Architectural Framework and Associated Load-Balancing Strategies and Algorithms via Parallel Simulation

Abstract

This paper first presents the requirements for and the architectural framework of a type of real-time parallel dataflow computer architecture, specifically, a Hybrid Data/Command Driven Architecture (HDCA). Application of such an architecture is discussed. Goals, strategies, and algorithms for both static load-balancing and dynamic resource allocation on an HDCA system are presented. A parallel simulation of an HDCA system employing the presented static load-balancing and dynamic resource allocation algorithms is developed and presented. The parallel simulation was executed on a parallel computer system for increased fidelity. Analysis of simulation results for two example applications of the architecture allowed verification of design goals and correct performance of the HDCA architectural framework and associated static load-balancing and dynamic resource allocation strategies and algorithms.
