Dynamic partitioning of shared cache memory
Webthe cache performance can be improved by partitioning a cache into dedicated areas for each process and a shared area. However, the partitioning was performed by collect-ing the miss-rate information of each process off-line. The work of [10] did not investigate how to partition the cache memory at run-time. WebApr 1, 2004 · dynamic partitioning of shared cache memory 15 Also, it is very difficult to control the cache a llocation at a block granularity. Therefore, we allocate chunks of cache blocks at a time ...

WebPDF - This paper proposes dynamic cache partitioning amongst simultaneously executing processes/threads. We present a general partitioning scheme that can be applied to set-associative caches. Since memory reference characteristics of processes/threads can change over time, our method collects the cache miss characteristics of … WebJan 20, 2014 · In order to reduce shared cache competitions in multicore processors and make page coloring-based cache partition more practical, this paper presents a malloc allocator-based cache partitioning mechanism with dynamic page coloring, in which memory allocated by our malloc allocator can be dynamically partitioned among different …
WebIn terms of cache replacement policies, we integrate our coor-dinated, dynamic cache partitioning technique with i) classic uncoordinated LRU replacement at each cache level, as well as ii) coordinated cache replacement based on demote hints from the bu er pool to the storage cache [32]. We show that our coordinated dynamic partitioning tech- WebThe Atlas consists of eight PUs, based on the Alpha 21164, connected via bidirectional ring, while the shared L2 cache and value/control predictor are accessible via two separate shared buses.

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 … WebCaching guidance. Cache for Redis. Caching is a common technique that aims to improve the performance and scalability of a system. It caches data by temporarily copying frequently accessed data to fast storage that's located close to the application. If this fast data storage is located closer to the application than the original source, then ...
