The last-level cache (LLC) of a modern chip-multiprocessor (CMP) keeps two kinds of data: shared data accessed by multiple cores and private data accessed by only one core. Although the former are likely to have a larger performance impact than the latter, the LLC manages both of those data in the same fashion. To realize a highly efficient execution on a CMP, this paper proposes a cache partitioning...
Analyzing parallel programs has become increasingly difficult due to the immense amount of information collected on large systems. In this scenario, cluster analysis has been proved to be a useful technique to reduce the amount of data to analyze. A good example is the use of the density-based cluster algorithm DBSCAN to identify similar single program multiple data (SPMD) computing phases in message-passing...
