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.

摘要： A mechanism is provided for managing a process-to-process inter-cluster communication request. A call from a first application is received in a first operating system in a first data processing system. The first operating system passes the call from the first operating system to a first host fabric interface controller in the first data processing system without processing the call. The first host fabric interface processes the call to determine a second data processing system in the plurality of data processing systems with which the call is associated, wherein the call is processed by the first host fabric interface without intervention by the first operating system. The first host fabric interface initiates an inter-cluster connection to a second host fabric interface in the second data processing. The call is then transferred to the second host fabric interface in the second data processing system via the inter-cluster connection.

摘要： In a multinode data processing system in which nodes exchange information over a network or through a switch, the mechanism which enables out-of-order data transfer via Remote Direct Memory Access (RDMA) also provides a corresponding ability to carry out broadcast operations, multicast operations, third party operations and conditional RDMA operations. In a broadcast operation a source node transfers data packets in RDMA fashion to a plurality of destination nodes. Multicast operation works similarly except that distribution is selective. In third party operations a single central node in a cluster or network manages the transfer of data in RDMA fashion between other nodes or creates a mechanism for allowing a directed distribution of data between nodes. In conditional operation mode the transfer of data is conditioned upon one or more events occurring in either the source node or in the destination 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： 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 mechanism is provided for managing an input/output device communication request. A first operating system passes a call from a first application intended for an input/output device in a second data processing system to a first host fabric interface controller in the first data processing system without processing the call. The first host fabric interface processes the call to determine the second data processing system with which the call is associated. The first host fabric interface initiates a connection to a second host fabric interface in the second data processing system and transfers the call to a second operating system associated with the input/output device in the second data processing system via the connection to the second host fabric interface. The second operating system then processes the call intended for the input/output device without assistance from any application running on the second data processing system.
