摘要： 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.

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： Tracking dynamic memory de-allocation using a single configuration table having a first register and a second register includes setting the first register as an active register, initiating a de-allocation of desired storage increments from a memory partition, setting the storage increments in the second register as invalid, purging all caches associated with the single configuration table, setting the second register as the active register and the first register as an inactive register, setting the desired storage increments in the first register as invalid, switching the active register from the second register to the first register to complete memory de-allocation using the single configuration table.

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.
摘要翻译：该方法包括：当处理器请求遇到本地高速缓存未命中时，向请求节点中的高速缓存发起处理器请求并将处理器请求广播到远程节点，执行每个远程高速缓存的目录搜索以确定目标行的地址的状态，以及指定地址的所有权状态，将目标行的状态返回到请求节点并形成组合响应，并将组合的响应广播到每个远程节点。在获取操作期间，当目录搜索指示远程节点上的IM或目标存储器节点时，数据来自相应的远程高速缓存并且在保护数据的同时被转发到请求节点，并且在存储操作期间，数据是源自请求节点，并且在一致性被建立之后被转发到IM或目标存储器节点时被保护。

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.

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： Embodiments relate to accessing a cache line on a multi-level cache system having a system memory. Based on a request for exclusive ownership of a specific cache line at the local node, requests are concurrently sent to the system memory and remote nodes of the plurality of nodes for the specific cache line by the local node. The specific cache line is found in a specific remote node. The specific remote node is one of the remote nodes. The specific cache line is removed from the specific remote node for exclusive ownership by another node. Based on the specified node having the specified cache line in ghost state, any subsequent fetch request is initiated for the specific cache line from the specific node encounters the ghost state. When the ghost state is encountered, the subsequent fetch request is directed only to nodes of the plurality of nodes.
