摘要： A mechanism is provided for managing a process-to-process communication request. A call is received in an operating system from an application in the data processing system. The operating system passes the call to a host fabric interface controller in the data processing system without processing the call. The host fabric interface controller processes the call using state information associated with the call. The call is processed by the host fabric interface controller without intervention by the operating system.

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.

摘要： A mechanism is provided for managing a process-to-process intra-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 controller processes the call without intervention by the first operating system to determine a second data processing system in the plurality of data processing systems with which the call is associated. The first host fabric interface controller initiates an intra-cluster connection to a second host fabric interface controller in the second data processing system. The first host fabric interface controller then transfers the call to the second host fabric interface controller in the second data processing system via the intra-cluster connection.

摘要： In a multinode data processing system in which the nodes communicate with one another through communication adapters coupled to a switch or network, a method is provided for using the Internet Protocol (IP) for transmitting large broadcast data packets without incurring the overhead normally associated with packet fragmentation. By adding an Internet Protocol (IP) header as the first header in every packet fragment in the fragmentation process, fragmented packets are able to be assembled in the IP layer without intervention at the adapter interface layer.

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： 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.
