Precursor Research

• Multi-computer operating system (1963-65)

  • Excitement and complexity

• Reconfigurable Multi-processor Architecture (1966-1972)

  • Dynamic Mapping of Process network on to Processor network

    • Hardware kernel micro-operating system
  • Mapping had to take into account of interrelationship among processes
  • Issues of scale

    • Control working set
  • Importance of careful attention to empirical data

    • Detail simulation
