Cluster controller for memory and data cache in a multiple cluster processing system

摘要

A cluster controller for controlling access to local memory and remote data cache in a multiple cluster computer system. In a multiple cluster computer system, a local memory in a cluster is part of the overall system address space. In order to manage local access as well as remote access to the local memory, the cluster controller maintains the responsibility of arbitrating the access to memory. Likewise, data from remote memory stored in the remote data cache is controlled by the cluster controller.
