    摘要： A distributed data processing system executes multiple tasks within a parallel job, including a first local task on a local node and at least one task executing on a remote node, with a remote memory having real address (RA) locations mapped to one or more of the source effective addresses (EA) and destination EA of a data move operation initiated by a task executing on the local node. On initiation of the data move operation, remote asynchronous data move (RADM) logic identifies that the operation moves data to/from a first EA that is memory mapped to an RA of the remote memory. The local processor/RADM logic initiates a RADM operation that moves a copy of the data directly from/to the first remote memory by completing the RADM operation using the network interface cards (NICs) of the source and destination processing nodes, determined by accessing a data center for the node IDs of remote memory.

    摘要： A data processing system enables global shared memory (GSM) operations across multiple nodes with a distributed EA-to-RA mapping of physical memory. Each node has a host fabric interface (HFI), which includes HFI windows that are assigned to at most one locally-executing task of a parallel job. The tasks perform parallel job execution, but map only a portion of the effective addresses (EAs) of the global address space to the local, real memory of the task's respective node. The HFI window tags all outgoing GSM operations (of the local task) with the job ID, and embeds the target node and HFI window IDs of the node at which the EA is memory mapped. The HFI window also enables processing of received GSM operations with valid EAs that are homed to the local real memory of the receiving node, while preventing processing of other received operations without a valid EA-to-RA local mapping.

    摘要： A method for handling multiple memory requests within a multi-processor system is disclosed. A lock control section is initially assigned to a data block within a system memory. In response to a request for accessing the data block by a processing unit, a determination is made whether or not the lock control section of the data block has been set. If the lock control section has been set, another determination is made whether or not the requesting processing unit is located beyond a predetermined distance from a memory controller. If the requesting processing unit is located beyond a predetermined distance from the memory controller, the requesting processing unit is invited to perform other functions; otherwise, the number of the requesting processing unit is placed in a queue table. However, if the lock control section has not been set, the lock control section of the data block is set, and the access request is allowed.

    摘要： A locking mechanism for supporting distributed computing within a multiprocessor system is disclosed. A lock control section and a stage control section are assigned to a data block within a system memory. In response to a request for accessing the data block by a processing unit, a determination is made by a memory controller whether or not the lock control section of the data block has been set. If the lock control section of the data block has been set, the access request is denied. Otherwise, if the lock control section of the data block has not been set, another determination is made whether or not a current processing stage of the requesting processing unit matches a processing stage indicated by the stage control section. If the current processing stage of the requesting processing unit does not match the processing stage indicated by the stage control section, the access request is denied; otherwise, the access request is allowed.

    摘要： A heterogeneous processing element model is provided where I/O devices look and act like processors. In order to be treated like a processor, an I/O processing element, or other special purpose processing element, must follow some rules and have some characteristics of a processor, such as address translation, security, interrupt handling, and exception processing, for example. The heterogeneous processing element model puts special purpose processing elements on the same playing field as processors, from a programming perspective, operating system perspective, and power perspective. The operating system can get work to a security engine, for example, in the same way it does to a processor.
