Abstract

The paper discusses the relationships between hierarchically composite MPP architectures and the software technology derived from the structured parallel programming methodology, in particular the architectural support to successive modular refinements of parallel applications, and the architectural support to the parallel programming paradigms and their combinations. The structured parallel programming methodology referred here is an application of the Skeletons model. The considered hierarchically composite architectures are MPP machine models for PetaFlops computing, composed of proper combinations of current architectural models of different granularities, where the Processors-In-Memory model is adopted at the finest granularity level. The methodologies are discussed with reference to the current PQE2000 Project on MPP general purpose systems
