摘要： Disclosed are a method of and system for multiple party communications in a processing system including multiple processing subsystems. Each of the processing subsystems includes a central processing unit and one or more network adapters for connecting said each processing subsystem to the other processing subsystems. A multitude of nodes are established or created, and each of these nodes is associated with one of the processing subsystems. A first aspect of the invention involves pipelined communication using RDMA among three nodes, where the first node breaks up a large communication into multiple parts and sends these parts one after the other to the second node using RDMA, and the second node in turn absorbs and forwards each of these parts to a third node before all parts of the communication arrive from the first node.

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 a multinode data processing system in which nodes exchange information over a network or through a switch, a structure and mechanism is provided within the realm of Remote Direct Memory Access (RDMA) operations in which DMA operations are present on one side of the transfer but not the other. On the side in which the transfer is not carried out in DMA fashion, transfer processing is carried out under program control; this is in contrast to the transfer on the DMA side which is characteristically carried out in hardware. Usage of these combination processes is useful in programming situations where RDMA is carried out to or from contiguous locations in memory on one side and where memory locations on the other side is noncontiguous. This split mode of transfer is provided both for read and for write operations.

摘要： A method is provided for sharing and/or transporting data within a single node of a multi-node data processing. The method avoids the necessity of making more than one copy of the data to be shared or transported. The method is tunable based on the size of the data segment involved. A shared memory area between tasks running in different address spaces on the node is used to coordinate the process and for task to task communication. The increase in efficiency provided by the intranodal process described herein also provides advantages to the internodal communication process since more CPU cycles are available for that aspect of system operation.
摘要翻译：提供了一种用于在多节点数据处理的单个节点内共享和/或传送数据的方法。该方法避免了要共享或传输数据的多个副本的必要性。该方法可以根据所涉及的数据段的大小进行调整。在节点上运行不同地址空间的任务之间的共享内存区域用于协调进程和任务进行任务通信。由于更多的CPU周期可用于系统操作的这一方面，由本文描述的内部结合处理提供的效率的提高也为节点间通信过程提供了优点。

摘要： Shared locks are employed for controlling a thread which extends across more than one protocol layer in a data processing system. The use of a counter is used as part of a data structure which makes it possible to implement shared locks across multiple layers. The use of shared locks avoids the processing overhead usually associated with lock acquisition and release. The thread which is controlled may be initiated in either an upper layer protocol or in a lower layer.
摘要翻译：共享锁用于控制在数据处理系统中跨越多于一个协议层延伸的线程。计数器的使用被用作数据结构的一部分，这使得可以跨多层实现共享锁。共享锁的使用避免了通常与锁获取和释放相关的处理开销。被控制的线程可以在上层协议或下层协议中启动。

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： In remote direct memory access transfers in a multinode data processing system in which the nodes communicate with one another through communication adapters coupled to a switch or network, failures in the nodes or in the communication adapters can produce the phenomenon known as trickle traffic, which is data that has been received from the switch or from the network that is stale but which may have all the signatures of a valid packet data. The present invention addresses the trickle traffic problem in two situations: node failure and adapter failure. In the node failure situation randomly generated keys are used to reestablish connections to the adapter while providing a mechanism for the recognition of stale packets. In the adapter failure situation, a round robin context allocation approach is used with adapter state contexts being provided with state information which helps to identify stale packets.
