WebFirst of all, knowing when to perform re-partitioning is non-trivial. Dynamic phase changing behaviors 1 of appli-cations lead to fluctuating resource demands, which may cause poor cache utilization under static partitioning. To re-partition the shared cache, we want to clearly capture program phase transitions on-the-fly. Even without phase WebJun 20, 2009 · Different memory access patterns can cause cache contention in different ways, and various techniques have been proposed to target some of these behaviors.
