Abstract: Disclosed are apparatuses, systems, and techniques that improve efficiency and decrease latency of remote direct memory access (RDMA) operations. The techniques include but are not limited to unified RDMA operations that are recognizable by various communicating devices, such as network controllers and target memory devices, as requests to establish, set, and/or update arrival indicators in the target memory devices responsive to arrival of one or more portions of the data being communicated.

Abstract: A Direct Memory Access (DMA) device includes an interface and a DMA engine. The interface is configured to communicate with a first memory and with a second memory. The DMA engine is configured to (i) receive a request to transfer data between the first memory and the second memory in accordance with a pattern of offsets to be accessed in the first memory or in the second memory, and (ii) transfer the data in accordance with the request.

Abstract: A Network-Connected Device (NCD) includes a network interface, a host interface, an NCD memory and an NCD processor. The network interface is configured for communicating over a network. The host interface is configured for communicating with a host. The NCD memory is configured to buffer packet information that originates from the host and pertains to a packet to be transmitted to the network at a specified transmission time. The NCD processor is configured to process the buffered packet information before the specified transmission time, and to transmit the packet to the network at the specified time. Processing of the packet information and transmission of the packet are decoupled from buffering of the packet information.

Abstract: A cross-network bridging apparatus includes a bus interface and bridging circuitry. The bus interface is configured for connecting to a system bus. The bridging circuitry is configured to translate between (i) system-bus transactions that are exchanged between one or more local devices that are coupled to the system bus and served by the system bus and one or more remote processors located across a network from the apparatus, and (ii) data units that convey the system-bus transactions, for transmitting and receiving as network packets over the network to and from the remote processors.
