posterIn chip multiprocessors, replication of cache lines is allowed to reduce the latency each core has to access a cache line. Because of this replication, it is possible for one copy of data to become out of date if another copy of that data is modified. How a MESI protocol accomplishes this: ? Keep a list of sharers for all cache lines ? Invalidate all L1s in the list of sharers on modify (write) request ? Forward read requests to whichever L1 has most recently modified the data As can be seen in the diagrams below, the frequency and degree of data sharing is not very high on average, so MESI might be overprovisioning for this uncommon case.
