    Abstract: A method for communication includes receiving at a receiving node over a network from a sending node a succession of data packets belonging to a sequence of transactions, including at least one or more first packets belonging to a first transaction and one or more second packets belonging to a second transaction executed by the sending node after the first transaction, wherein at least one of the second packets is received at the receiving node before at least one of the first packets. At the receiving node, upon receipt of the data packets, data are written from the data packets in the succession to respective locations in a buffer. Execution of the second transaction at the receiving node is delayed until all of the first packets have been received and the first transaction has been executed at the receiving node.

    Abstract: Apparatus, systems, and methods are described, including apparatus that includes one or more communication interfaces for communicating over a communication network, and a processor. The processor is configured to receive, via the communication interfaces, a plurality of numbers, and calculate a sum of the numbers that is independent of an order in which the numbers are received, by (i) converting any of the numbers that are received in a floating-point representation to a derived floating-point representation that includes a plurality of signed integer multiplicands corresponding to different respective orders of magnitude, and (ii) summing the numbers in the derived floating-point representation, by separately summing integer multiplicands that correspond to the same order of magnitude. Other embodiments are also described.

    IPC: H04J3/06

    Abstract: A network device includes a port, a transmission pipeline and a time-stamping circuit. The port is configured for connecting to a network. The transmission pipeline includes multiple pipeline stages and is configured to process packets and to send the packets to the network via the port. The time-stamping circuit is configured to temporarily suspend at least some processing of at least a given packet in the transmission pipeline, to verify whether a pipeline stage having a variable processing delay, located downstream from the time-stamping circuit, meets an emptiness condition, and, only when the pipeline stage meets the emptiness condition, to time-stamp the given packet and resume the processing of the given packet.

    Abstract: A method for communication includes establishing, using an end-to-end reliable transport context, a channel for exchange of data packets over a network between a first network interface controller (NIC) of a first computing node on the network and a second NIC of a second computing node on the network. The first NIC accepts first and second work items for execution on behalf of different, first and second sender processes, respectively, that are running on the first computing node. The first and second work items are executed by transmitting over the network from the first NIC to the second NIC, using the end-to-end reliable transport context, first and second messages directed to different, first and second receiver process running on the second computing node, using the same end-to-end reliable transport context. The second message is sent before receiving from the second NIC any acknowledgment of the first message.

    Abstract: A method for steering packets includes receiving a packet and determining parameters to be used in steering the packet to a specific destination, in one or more initial steering stages, based on one or more packet specific attributes. The method further includes determining an identity of the specific destination of the packet in one or more subsequent steering stages, governed by the parameters determined in the one or more initial stages and one or more packet specific attributes, and forwarding the packet to the determined specific destination.
