摘要： 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.

摘要： A high speed remote storage controller system for a computer system has cluster nodes of symmetric multiprocessors. A plurality of clusters of symmetric multiprocessors each of has a plurality of processors, a shared cache memory, a plurality of I/O adapters and a main memory accessible from the cluster. Each cluster has an interface for passing data between cluster nodes of the symmetric multiprocessor system. Each cluster has a local interface and interface controller. The system provides one or more remote storage controllers each having a local interface controller and a local-to-remote data bus. A remote resource manager manages the interface between clusters of symmetric multiprocessors. The remote store controller is responsible for processing data accesses across a plurality of clusters and processes data storage operations involving shared memory. A macro is provided for processing a plurality of simultaneous data storage operations either synchronously through interaction with a sequential multistage centralized pipeline to serialize requests and provide address interlocking services or asynchronously whereby main memory accesses bypass a centralized system pipeline. These accesses can occur in parallel with other remote storage operations.

摘要： A bus protocol is disclosed for a symmetric multiprocessing computer system consisting of a plurality of nodes, each of which contains a multitude of processors, I/O devices, main memory and a system controller comprising an integrated switch with a top level cache. The nodes are interconnected by a dual concentric ring topology. The bus protocol is used to exchange snoop requests and addresses, data, coherency information and operational status between nodes in a manner that allows partial coherency results to be passed in parallel with a snoop request and address as an operation is forwarded along each ring. Each node combines it's own coherency results with the partial coherency results it received prior to forwarding the snoop request, address and updated partial coherency results to the next node on the ring. The protocol allows each node in the system to see the final coherency results without requiring the requesting node to broadcast these results to all the other nodes in the system. The bus protocol also allows data to be returned on one of the two rings, with the ring selection determined by the relative placement of the source and destination nodes on each ring, in order to control latency and data bus utilization.

摘要： Embodiments relate to storing data to a system memory. An aspect includes accessing successive entries of a cache directory having a plurality of directory entries by a stepper engine, where access to the cache directory is given a lower priority than other cache operations. It is determined that a specific directory entry in the cache directory has a change line state that indicates it is modified. A store operation is performed to send a copy of the specific corresponding cache entry to the system memory as part of a cache management function. The specific directory entry is updated to indicate that the change line state is unmodified.

摘要： The method includes initiating a processor request to a cache in a requesting node and broadcasting the processor request to remote nodes when the processor request encounters a local cache miss, performing a directory search of each remote cache to determine a state of a target line's address and an ownership state of a specified address, returning the state of the target line to the requesting node and forming a combined response, and broadcasting the combined response to each remote node. During a fetch operation, when the directory search indicates an IM or a Target Memory node on a remote node, data is sourced from the respective remote cache and forwarded to the requesting node while protecting the data, and during a store operation, the data is sourced from the requesting node and protected while being forwarded to the IM or the Target Memory node after coherency has been established.

摘要： A method of preventing lockout and stalling conditions in a multi-node system having a plurality of nodes which includes initiating a processor request to a shared level of cache in a requesting node, performing a fabric coherency establishment sequence on the plurality of nodes, issuing a speculative memory fetch request to a memory, detecting a conflict on one of the plurality of nodes and communicating the conflict back to the requesting node within the system, canceling the speculative memory fetch request issued, and repeating the fabric coherency establishment sequence in the system until the point of conflict is resolved, without issuing another speculative memory fetch request. The subsequent memory fetch request is only issued after determining the state of line within the system, after the successful completion of the multi-node fabric coherency establishment sequence.
