摘要： Intra-node data transfer in collective communications is facilitated. A memory object of one task of a collective communication is concurrently attached to the address spaces of a plurality of other tasks of the communication. Those tasks that attach the memory object can access the memory object as if it was their own. Data can be directly written into or read from an application data structure of the memory object by the attaching tasks without copying the data to/from shared memory.

摘要： A method is provided for operating a communications adapter employed in a multinode data processing system in a fashion which enhances the performance of remote direct memory access data transfers. The system is provided with pointers and a table which are employed to determine whether or not an address which has been supplied for the transfer has already been mapped to a real address at the source or destination node. The table is also preferably provided with counters which can be incremented or decremented to enable the use of least recently used mechanisms at the upper level protocol layers to more efficiently control the setting and resetting of table entries.

摘要： In a transmission protocol in which a user running an application in an address space in one data processing system wishes to transmit a data packet to another address space in another data processing system by means of direct memory access directly from a sending buffer to a receiving buffer with no copy, a mechanism is provided for minimizing the need for retransmission and for insuring proper entry into the target data processing system address space. In particular, when the first system does not receive an acknowledgment from the receiver, a special data packet with a retransmit flag bit set is sent to the second system. When this system receives the data packet with the retransmit flag bit set the second system responds either by sending a new acknowledgment or by sending a request for retransmission. No transmission back to the first system occurs, however before such a request is made and in fact the receiving system does not send this retransmission request without insuring that its receipt would be appropriate. In particular, the second system, before requesting retransmission, checks to assure that tag association is still valid so that an adapter at the second system is still capable of matching tags in data packet headers with appropriate real address memory locations within address spaces belonging to the second receiving data processing system. In this manner needless retransmission of packets does not occur and retransmission occurs only when receipt of the data packet is appropriate.

摘要： While an asynchronous memory move (AMM) operation is ongoing, a prefetch request for data from the source effective address or the destination effective address triggers cache injection by the AMM mover of relevant data from the stream of data being moved in the physical memory. The memory controller forwards the first prefetched line to the prefetch engine and L1 cache, the next cache lines in the sequence of data to the L2 cache, and a subsequent set of cache lines to the L3 cache. The memory controller then forwards the remaining data to the destination memory location. Quick access to prefetch data is enabled by buffering the stream of data in the upper caches rather than placing all the moved data within the memory. Also, the memory controller places moved data into only a subset of the available cache lines of the upper level cache.
摘要翻译： 当异步存储器移动（AMM）操作正在进行时，来自源有效地址或目的地有效地址的数据的预取请求触发AMM移动器对来自物理存储器中移动的数据流的相关数据的高速缓存注入。 存储器控制器将第一预取行转发到预取引擎和L1高速缓存，将数据序列中的下一个高速缓存行转发到L2高速缓存，以及将后续的一组高速缓存行转发到L3高速缓存。 存储器控制器然后将剩余的数据转发到目的地存储器位置。 通过缓存高速缓存中的数据流，而不是将所有移动的数据放在内存中，可以快速访问预取数据。 此外，存储器控制器将移动的数据仅放置在高级缓存的可用高速缓存行的子集中。

摘要： A method within a data processing system by which a processor executes an asynchronous memory move (AMM) store (ST) instruction to complete a corresponding AMM operation in parallel with an ongoing (not yet completed), previously issued barrier operation. The processor receives the AMM ST instruction after executing the barrier operation (or SYNC instruction) and before the completion of the barrier operation or SYNC on the system fabric. The processor continues executing the AMM ST instruction, which performs a move in virtual address space and then triggers the generation of the AMM operation. The AMM operation proceeds while the barrier operation continues, independent of the processor. The processor stops further execution of all other memory access requests, excluding AMM ST instructions that are received after the barrier operation, but before completion of the barrier operation.

摘要： A protocol interface is provided for an active message protocol of a computing environment and a client process employing the active message protocol. The protocol interface includes an interface to a header handler function associated with the client process. The interface to the header handler function has parameters to be passed by and a parameter to be returned to the active message protocol when processing a message received through the active message protocol. The parameters to be passed include current message state information and current message type information for the received message. These parameters facilitate message-specific decisions by the header handler function about processing data of the message by the active message protocol. The parameter to be returned to the active message protocol instructs the active message protocol how to process the received message other than just where to store the message.

摘要： A method and system for transferring noncontiguous messages group including assembling a set of data into a series of transmission packets, packaging a description of the layout of the transmission packets into description packets and then places each description packet into a local buffer while maintaining a count of the number of description packets, transfers each description packet into a transmit buffer for transmission to at least one receiving node, identifies the data packets, and forwards each data packet to the transmit buffer for transmission to the at least one receiving node. The receiving node receives the transmission packets, identifies each packet as a description packet or data packet, places the description packets in a local buffer for storage until the description is complete, places each description packet into a user data buffer, stores data packets in a local queue until the description is complete, then transfers the data packets to the user buffer.

摘要： In remote direct memory access (RDMA) transfers in a multinode data processing system in which the nodes communicate with one another through communication adapters coupled to a switch or network, there is a need for the system to ensure efficient memory protection mechanisms across jobs. A method is thus desired for addressing virtual memory on local and remote servers that is independent of the process ID on the local and/or remote node. The use of global Translation Control Entry (TCE) tables that are accessed/owned by RDMA jobs and are managed by a device driver in conjunction with a Protocol Virtual Offset (PVO) address format solves this problem.
