    Abstract: A computer peripheral device includes a host interface, which is configured to communicate over a bus with a host processor and with a system memory of the host processor. Processing circuitry in the peripheral device is configured to receive and execute work items submitted to the peripheral device by client processes running on the host processor, and responsively to completing execution of the work items, to write completion reports to the system memory, including first completion reports of a first data size and second completion reports of a second data size, which is smaller than the first data size.

    Abstract: A method for communication, includes allocating, in a network interface controller (NIC) a single dynamically-connected (DC) initiator context for serving requests from an initiator process running on the initiator host to transmit data to multiple target processes running on one or more target nodes. The NIC transmits a first connect packet directed to a first target process and referencing the DC initiator context so as to open a first dynamic connection with the first target process. The NIC receives over the packet network, in response to the first connect packet, a first acknowledgment packet containing a first session identifier (ID). Following receipt of the first acknowledgment packet, the NIC transmits one or more first data packets containing the first session ID over the first dynamic connection from the NIC to the first target process. Dynamic connections with other target processes may subsequently be handled in similar fashion.

    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 translation: 一种用于通信的方法包括在接收节点通过网络从发送节点接收属于事务序列的一系列数据分组，包括属于第一事务的至少一个或多个第一分组和属于第一事务的一个或多个第二分组 在所述第一事务之后由所述发送节点执行的第二事务，其中在所述第一分组中的至少一个之前在所述接收节点处接收所述第二分组中的至少一个。 在接收节点，在接收到数据分组时，将数据从连续的数据分组写入缓冲器中的相应位置。 在接收节点处的第二事务的执行被延迟，直到已经接收到所有第一个分组并且已经在接收节点处执行了第一个事务。

    Abstract: A Network Interface (NI) includes a host interface, which is configured to receive from a host processor of a node one or more cross-channel work requests that are derived from an operation to be executed by the node. The NI includes a plurality of work queues for carrying out transport channels to one or more peer nodes over a network. The NI further includes control circuitry, which is configured to accept the cross-channel work requests via the host interface, and to execute the cross-channel work requests using the work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation.
