Adaptive Block Pinning Based: Dynamic Cache Partitioning for Multi-Core Architectures

This paper is aimed at exploring the various techniques currently used for partitioning last level (L2/L3) caches in multicore architectures, identifying their strengths and weaknesses and thereby proposing a novel partitioning scheme known as Adaptive Block Pinning which would result in a better utilization of the cache resources in CMPs. The widening speed gap between processors and memory along with the issue of limited on-chip memory bandwidth make the last-level cache utilization a crucial factor in designing future multicore processors. Contention for such a shared resource has been shown to severely degrade performance when running multiple applications. As architectures incorporate more cores, multiple application workloads become increasingly attractive, further exacerbating contention at the last-level cache.
