Abstract :
Some aspects of a long-term parallel-processing research project (PACS, Pax, and Qcd Pax) begun in 1977 at Kyoto University and Hitachi Corporation´s Nuclear Power Division are discussed. The discussion is based on an analysis of a number of papers, a book detailing this work, several visits to the project laboratory in Japan, and an examination of some programs that now run on cd Pax. The initial name, processor array for continuum simulation (PACS), was soon changed to Processor Array experiment, or Pax. Qcd Pax (for quantum chromodynamics) is the current running computer. The characteristics of the family are described, and the hardware, communication, and memory functions of the host computer, the use of four levels of parallelism programming, and performance are examined.<>
