Architectural Patterns for Parallel Programming: Models for Performance Estimation

The Architectural Performance Modelling Method is presented as a criteria for selecting the organisation of a parallel program based on estimating its probable performance. An Architectural Performance Model is based on selecting from the Architectural Patterns for Parallel Programming (descriptions of coodinations commonly used in Parallel Programming), a component simulator (representing a simulation of a processing component's behaviour), and a performance analysis of parallel applications (in which the information on system performance is examined). Parallel programs simulated using the Architectural Performance Modelling Method range from a complete parallel program to a partially implemented program design. The simulation of parallel systems, using the information about the problem to be solved, the available resources, and architectural patterns describing overall coordinations of the parallel programs, makes it possible to identify the best performing architectural solution for the system being built.
