Abstract: This disclosure describes techniques for a network interface controller (NIC) to communicate over a network according to a specified transmission communication protocol. The NIC receives, from a host processor, an indication of a data unit and an indication of a header template. The NIC generates, independent of the specified transmission communication protocol, metadata for transmitting a segment of the data unit over a network. The NIC generates, at last partly using the metadata, header fields that comply with the specified transmission communication protocol. The NIC processes the header template and the header fields to generate a packet header, and the NIC transmits, over the network, a packet including the packet header and the segment of the data unit.

Abstract: An improved communication system for the prevention of lockup in a computer system of the binary n-cube type. Input circuitry at each of the nodes is connected for receiving messages and includes an input buffer for initially receiving the messages. Output circuitry at each of the nodes is connected for transmitting holding the messages prior to and during transmission thereof. A kernel program at each of the nodes acts as an interface between the user process programs and exclusively controls the receiving and transmitting of messages into and out of the node. There is provision for the user process programs to pass control to the kernel program to request the sending and receiving of messages by the kernel program. A lock bit is associated with each message, sensible by the user process programs, and reset by the kernel program when the kernel program has transferred the associated message.
