Intel Paragon XP/S - Architecture, Software Environment, and Performance

摘要

The paper describes the hardware and software components of the Intel Paragon XP/S system, a distributed-memory scalable multicomputer. The Paragon processing nodes, which are based on the Intel i860 XP RISC processor, are connected by a two-dimensional mesh with high bandwidth. The paper first gives an overview of the Paragon system architecture, the node architecture, the interconnection network, I/O interfaces, and peripherals. The second part outlines the Paragon OSF/1 operating system and the program development environment including programming models, compilers, application libraries, and tools for parallelization, debugging, and performance analysis. The third part includes performance measurements characterizing the interconnection network, input/output, and numerical performance.
