Evaluation studies Owicki & Agarwal's study

Results

• for common bus based system:
  • No-cache scheme has the worst performance, while Dragon scheme has the best
  • SW-flush is comparable with Dragon for applications with infrequent access to shared data
  • SW flush is better then Dragon for workload with relatively large number of references to a shared data before the flush

• for multistage ICN based system:
  • processing power of the SW scheme increases linearly with the number of processors - scalable scheme
