Matching architecture and software technology for HPC systems

PQE2000 is an Italian project on High Performance Computing (HPC), whose goal is the realization of innovative general purpose systems and programming tools, as well as the development of new strategic HPC applications for industry, commerce and public services. The research activities of PQE2000 include MPP architecture, software tools and programming environments, and applications in technical, transactional and new media areas. The results of these activities are transferred into industrial products. This paper describes the general guidelines, the current products and technologies of PQE2000, and the trends in the area of relationships between programming environments and architectural models for the efficient exploitation of large degree of variable grain parallelism in complex applications.
