Non-Uniform Cache Access (NUCA) architectures provide a potential solution to reduce the average latency for the Last-Level-Cache (LLC), where the cache is organized into per-core local and remote partitions. Recent paper has demonstrated the benefits of cooperative cache sharing among local and remote partitions. However, ignoring cache access patterns of concurrently executing applications sharing the local and remote partitions can cause inter-partition contention that reduces the overall instruction throughput. The authors propose a dynamic cache management scheme for LLC in NUCA-based architectures, which reduces inter-partition contention.
