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： 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 a multinode data processing system in which nodes exchange information over a network or through a switch, a structure and mechanism are provided which enables data packets to be sent and received in any order. Normally, if in-order transmission and receipt are required, then transmission over a single path is essential to insure proper reassembly. However, the present mechanism avoids this necessity and permits Remote Direct Memory Access (RDMA) operations to be carried out simultaneously over multiple paths. This provides a data striping mode of operation in which data transfers can be carried out much faster since packets of single or multiple RDMA messages can be portioned and transferred over several paths simultaneously, thus providing the ability to utilize the full system bandwidth that is available.

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 barrier synchronization register, accessible to the nodes in a distributed data processing system, has portions thereof allotted to threads which are present in multiple groups. The barrier synchronization register portion allotted to a given thread has stored therein, over time, group identifier numbers. In this way the state space of a barrier synchronization register is shared over more than one group of process threads.

摘要： A system and method to provide injection of important data directly into a processor's cache location when that processor has previously indicated interest in the data. The memory subsystem at a target processor will determine if the memory address of data to be written to a memory location associated with the target processor is found in a processor cache of the target processor. If it is determined that the memory address is found in a target processor's cache, the data will be directly written to that cache at the same time that the data is being provided to a location in main memory.
