Abstract [en]

The introduction of multicores has made analysis of shared  resources, such as shared caches and shared DRAM bandwidth, an  important topic to study. We present two simple, but accurate, cache  sharing models that use high-level data that can easily be measured  on existing systems. We evaluate our model using a simulated  multicore processor with four cores and a shared L2 cache. Our  evaluation shows that we can predict average sharing in groups of  four benchmarks with an average error smaller than 0.79% for random caches and 1.34% for LRU caches.
