Dynamic partitioning of shared cache memory
WebAs shown in Fig. 1, the shared cache is partitioned in the ways. Each core can dynamically tune the number of selective-ways. For example, core 2 can select the 3rd and 6th way by calling the ... WebDynamic partitioning of shared caches has been proposed to improve performance of traditional eviction policies in modern multi- ... an L2 miss occurs. After some cycles, commit stops. When the cache line comes from main memory, commit ramps up to its steady state value. As a consequence, an isolated L2 miss has a higher impact on performance ...

WebShared cache interference in multi-core architectures has been recognized as one of major factors that degrade predictability of a mixed-critical real-time system. ... In this paper, we present a dynamic partitioned cache memory for mixed-critical real-time multi-core systems. ... M. Caccamo, L. Sha and J. Martinez, Impact of cache partitioning ... 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
WebMulti-core processors with shared last-level caches are vulnerable to performance inefficiencies and fairness issues when the cache is not carefully managed between the multiple cores. Cache partitioning is an effective … WebDynamic cache partitioning for shared Last Level Caches (LLC) is deployed in most modern multicore systems to achieve process isolation and fairness among the applications and avoid security threats. Since LLC has visibility of all cache blocks requested by several applications running on a multicore system, a malicious application can potentially …
WebSymbiotic resource partitioning (SRP) proposed in this paper avoids the scenarios of multiple applications exercising the off-chip memory bandwidth simultaneously by appropriately controlling the cache partitioning. In order to control the cache partitioning, SRP employs an empirical model that relies on a metric (last level cache misses per ...
