Min & Baer’s study

Goals, methodology, conditions, and metrics

• comparison of HW (centralized full-map directory) versus SW (timestamp) scheme

• simulation based on real address traces

• used applications characterized by DoAll loops model of parallelism

• conditions of simulation:

  • prescheduled processes:
    i-th iteration on the processor (i mod P) +1; P=number of processors
  • randomly scheduled processes

• performance measures: miss ratio, write traffic, and network traffic
