摘要： A method of communication includes receiving, in a network interface device, first and second requests from an initiator process running on an initiator host to transmit, respectively, first and second data to first and second target processes running on one or more target nodes, via a packet network. A single dynamically-connected initiator context is allocated for serving both the first and second requests. A first connect packet referencing the dynamically-connected (DC) initiator context is directed to the first target process so as to open a first dynamic connection with the first target process, followed by transmission of the first data over the first dynamic connection. The first dynamic connection is closed after the transmission of the first data, and a second connect packet is transmitted so as to open a second dynamic connection with the second target process, followed by transmission of the second data.

摘要： A network interface adapter includes a network interface and a client interface, for coupling to a client device so as to receive from the client device work requests to send messages over the network using a plurality of transport service instances. Message processing circuitry, coupled between the network interface and the client interface, includes an execution unit, which generates the messages in response to the work requests and passes the messages to the network interface to be sent over the network. A memory stores records of the messages that have been generated by the execution unit in respective lists according to the transport service instances with which the messages are associated. A completion unit receives the records from the memory and, responsive thereto, reports to the client device upon completion of the messages.

摘要： An input/output (I/O) device includes a host interface for connection to a host device having a memory, and a network interface, which is configured to transmit and receive, over a network, data packets associated with I/O operations directed to specified virtual addresses in the memory. Processing circuitry is configured to translate the virtual addresses into physical addresses using memory keys provided in conjunction with the I/O operations and to perform the I/O operations by accessing the physical addresses in the memory. At least one of the memory keys is an indirect memory key, which points to multiple direct memory keys, corresponding to multiple respective ranges of the virtual addresses, such that an I/O operation referencing the indirect memory key can cause the processing circuitry to access the memory in at least two of the multiple respective ranges.

摘要： A method for operating a peripheral device includes receiving at the peripheral device service orders, which are identified with respective service instances and are submitted to the peripheral device over the bus by software applications running on a host processor, which write copies of the service orders to a memory. The received service orders are queued for execution by the peripheral device. When one or more of the service orders have been dropped from the queue prior to execution, a recovery of a selected service instance is initiated by submitting a read request from the peripheral device to the memory over the bus to receive a copy of any unexecuted service order associated with the service instance.

摘要： A method of direct memory access (DMA) includes receiving a first notification at a DMA engine that a first list of descriptors has been prepared, each of the descriptors in the list including an instruction for execution by the DMA engine and a link to a succeeding one of the descriptors, except for a final descriptor in the list, which has a null link. The DMA engine reads and executes the descriptors in the first list. When the DMA engine receives a second notification that a second list of the descriptors has been prepared, it rereads at least a part of the final descriptor in the first list to determine a changed value of the link, indicating a first descriptor in the second list. It then reads and executes the descriptors in the second list responsive to the changed value of the link.

摘要： An input/output (I/O) device includes a memory buffer and off-loading hardware. The off-loading hardware is configured to accept from a host a scatter/gather list including one or more entries. The entries include at least a pattern-type entry that specifies a period of a periodic pattern of addresses that are to be accessed in a memory of the host. The off-loading hardware is configured to transfer data between the memory buffer of the I/O device and the memory of the host by accessing the addresses in the memory of the host in accordance with the periodic pattern at intervals indicated in the period.
