| Popis: | 98 In this thesis, we first characterize two popular benchmark suites, PARSEC and SPLASH-2. Different configurations of the simulated machine are set for each workload in the suites to study their diverse properties. Besides, we also try to evaluate the influence of different workloads when enabling a software prefetching scheme. Based on the experiments, we find that there is plenty of shared read traffic on the interconnection in these workloads. To reduce these shared read misses, a policy, called Snooping Fetch (SF), is proposed for the shared data in parallelized applications, which takes advantage of the inherent cache coherence protocol and the broadcasting information from the snooping protocol. The SF policy utilizes the broadcasting property to fetch shared data before the data is actually needed. In our experiments, the SF policy provides a reduction potential of 8% in average in the amounts of L1 cache misses, a reduction potential of 0.5% in average in the L1 cache miss rate, and a potential of 0.4% speedup in average. |
