Abstract
A remote resource management system for managing resources in a symmetrical multiprocessing environment having a plurality of clusters of symmetric multiprocessors each of which provides interfaces between cluster nodes of the symmetric multiprocessor system with a local interface and an interface controller. One or more remote storage controllers each has a local interface controller and a local-to-remote data bus. A remote fetch controller is responsible for processing data accesses across the clusters and a remote store controller is responsible for processing data accesses across the clusters. These controllers work in conjunction to provide a deadlock avoidance system for preventing hangs.
