摘要 A method and structure for a system for maintaining coherence of cache lines in a shared memory multiplexor system comprises a system area network and a plurality of compute nodes connected to the system area network. Each of the computer nodes includes a local main memory, a local shared cache and a local coherence controller and computer nodes external to a given compute node include external shared caches and the coherence controller includes shadow directories, each corresponding to one of the external shared caches. Each of the shadow directories includes state information of the local main memory cached in the external shared caches. The shadow directories include only state information of the local main memory cached in the external shared caches.
