    Abstract: A method and system are provided for limiting unnecessary data traffic on the data communication connections connecting various system components, including the various levels of system memory. Some embodiments may include processing a buffer allotment request and/or a buffer release command in coordination with a system or network operation requiring temporary storage of data in a memory buffer. The buffer allotment request may be capable of indicating the amount of storage space required on the memory buffer to execute the system or network operation. The system may be capable of precluding the system or network operation from executing until there is sufficient space in the memory buffer to complete the operation without evicting operational data from the memory buffer. In some embodiments, the buffer release command may signal completion of the system or network operation and release of the utilized memory buffer space for other operations.

    Abstract: A network adapter includes a port and one or more circuits. The port communicates packets over a network in which switches forward packets in accordance with tuples of the packets. The one or more circuits are to hold a user-programmable scheme specifying assignments of the packets of a given flow destined to a peer node to sub-flows having respective different tuples, assign first packets of the given flow to one or more of the sub-flows in accordance with the user-programmable scheme, by setting respective tuples of the first packets, transmit the first packets to the peer node via the port, monitor notifications received from the network, the notifications being indicative of respective states of the sub-flows, based on the notifications and on the user-programmable scheme determine an assignment of second packets of the given flow to the sub-flows, and transmit the second packets to the peer node via the port.

    Abstract: Methods, systems, and computer program products for selecting packing processing cores are provided. An example system includes a plurality of packet processing cores and a load balancing unit communicatively connected to the plurality of packet processing cores. The load balancing unit is configured to receive a workflow packet including packet description data indicative of at least a packet structure and a packet priority and receive, from the plurality of packet processing cores, state data indicative of at least a utilization state and an operating state of each of the respective packet processing cores. The load balancing unit determines a selected packet processing core from amongst the plurality of packet processing cores based on the state data of the packet processing core and the packet description data of the workflow packet and transmits the workflow packet to the selected packet processing core.

    Abstract: A method for communication includes receiving in a network device work requests posted by a host processor to perform a series of communication transactions, including at least a first transaction and a second transaction comprising first and second operations to be executed in a sequential order in response to corresponding first and work requests posted by the host processor. In response to the work requests, data packets are transmitted over a network from the network device to a destination node and corresponding responses are received from the destination node. Based on the received responses, completion of the first operations in the first transaction is reported from the network device to the host processor according to the sequential order, and completion of the second operation in the second transaction is reported from the network device to the host processor regardless of whether the first transaction has been completed.
