State-of-the-art multiprocessor cache hierarchies propagate the use of a fixed granularity in the cache organization to the design of the coherence protocol. Unfortunately, the fixed granularity, generally chosen to match average spatial locality across a range of applications, not only results in wasted bandwidth to serve an individual thread's access needs, but also results in unnecessary coherence traffic for shared data. The additional bandwidth has a direct impact on both the scalability of parallel applications and overall energy consumption.
