Abstract
A remote resource management system for managing resources in a symmetrical multiprocessing comprising a plurality of clusters of symmetric multiprocessors having interfaces between cluster nodes of the symmetric multiprocessor system. Each cluster of the system has a local interface and interface controller. There are one or more remote storage controllers each having its local interface controller, and a local-to-remote data bus. The remote resource manager manages the interface between two clusters of symmetric multiprocessors each of which clusters has a plurality of processors, a shared cache memory, a plurality of I/O adapters and a main memory accessible from the cluster. This remote resource manager manages resources with a remote storage controller to distribute work to a remote controller acting as an agent to perform a desired operation without requiring knowledge of a requester who initiated the work request. Said work is transferred only when a remote requester is available for processing of the work, without a need for constant communication between the clusters of symmetric multiprocessors.
