ParaDiGM: A Highly Scalable Shared-Memory Multi-Computer Architecture

摘要

ParaDiGM is a highly scalable shared-memory multi-computer architecture. It isbeing developed to demonstrate the feasibility of building a relatively low-cost shared-memory parallel computer that scales to large configurations, and yet provides sequential programs with performance comparable to a high-end microprocessor. A key problem is building a scalable memory hierarchy. In this paper we describe the ParaDiGm architecture, highlighting the innovations of our approach and presenting results of our evaluation of the design. We envision that scalable shared-memory multiprocessors like ParaDiGm will soon become the dominant form of parallel processing, even for very large-scale computation, providing a uniform platform for parallel programming systems and applications.
