The work
CARE is a concurrency-aware cache management framework published at HPCA 2023 by Xiaoyang Lu, Rujia Wang, and Xian-He Sun: CARE: A Concurrency-Aware Enhanced Lightweight Cache Management Framework. It starts from the observation that data access concurrency, in addition to locality, matters for cache performance, since a lower miss rate does not always mean better overall performance. CARE introduces the pure miss contribution (PMC) metric, which measures the cost of each outstanding miss while accounting for concurrency, and uses it to manage the cache.
