In this paper we introduce a new classification of misses in shared-memory multiprocessors based on interprocessor communication. We identify the set of essential misses, i.e., the smallest set of misses necessary for correct execution. Essential misses include cold misses and true sharing misses. All other misses are useless misses and can be ignored without affecting the correctness of program execution. Based on the new classification we compare the effectiveness of five different protocols which delay and combine invalidations leading to useless misses. In cache-based systems the protocols are very effective and have miss rates close to the essential miss rate. In virtual shared memory systems the techniques are also effective but leave room for improvements.
