ABSTRACT:
Write transactions with large amounts of data using a typical cache may consume over half of the available backing store bandwidth because of the way traditional caching algorithms fill lines during a write-invoked eviction. Relaxing the traditional constraint of cache coherency improves write performance by eliminating unneeded cache line fills. This technique conserves backing store bandwidth during many write operations while having negligible impact on the cache's read performance.
