To maintain coherence in conventional shared-memory multiprocessor systems, processors first check other processors' caches before obtaining data from memory. This coherence checking adds latency to memory requests and leads to large amounts of interconnect traffic in broadcastbased systems. Our results for a set of commercial, scientific and multiprogrammed workloads show that on average 67% (and up to 94%) of broadcasts are unnecessary. Coarse-Grain Coherence Tracking is a new technique thatdoi:10.1109/isca.2005.31 dblp:conf/isca/CantinLS05 fatcat:x5574s4kxba3bab65cx2l5i4xa
