<p>Multiprocessor system having distributed shared resources and dynamical and selective global data replication in which a plurality of processors (CPU0,1,2,3) communicate each with the other through a system bus (5), each CPU (CPU0,1,2,3) is provided with a local memory 8 storing data used locally and global data shareable by a plurality of processes operative in differing CPUs and therefore replicated in the local memory of each CPU, and in which global data replication is performed, at page level only when a global data page is effectively needed by a plurality of processes operative in differing CPUs and in those CPUs where the page is needed, the replication in the other CPUs being performed in a predetermined trash page 8C of the local memory so that memory space required for replication is minimized as well as traffic on the system bus for global data replication and global data writes required for assuring global data consistency. <IMAGE></p> |
