    摘要： Apparatus for data communications includes a host interface, which is configured to be connected to a bus of a host computer having a processor and a memory. Processing circuitry, which is coupled to the host interface, is configured to receive video data with respect to a sequence of pixels, the video data including data words of more than eight bits per pixel for at least one pixel component of the pixels, and to write the video data, via the host interface, to at least one buffer in the memory while justifying the video data in the memory so that the successive pixels in the sequence are byte-aligned in the at least one buffer.

    摘要： A switch in a data network is configured to mediate data exchanges among network elements. The apparatus further includes a processor, which organizes the network elements into a hierarchical tree having a root node network element, vertex node network elements, and child node network elements that include leaf node network elements. The leaf node network elements are originate aggregation data and transmit the aggregation data to respective parent vertex node network elements. The vertex node network elements combine the aggregation data from at least a portion of the child node network elements, and transmit the combined aggregation data from the vertex node network elements to parent vertex node network elements. The root node network element is operative for initiating a reduction operation on the aggregation data.

    摘要： A method in a system that includes first and second devices that communicate with one another over a fabric that operates in accordance with a fabric address space, and in which the second device accesses a local memory via a local connection and not over the fabric, includes sending from the first device to a translation agent (TA) a translation request that specifies an untranslated address in an address space according to which the first device operates, for directly accessing the local memory of the second device. A translation response that specifies a respective translated address in the fabric address space, which the first device is to use instead of the untranslated address is received by the first device. The local memory of the second device is directly accessed by the first device over the fabric by converting the untranslated address to the translated address.

    摘要： A method for data storage includes configuring a driver program on a host computer to receive commands in accordance with a protocol defined for accessing local storage devices connected to a peripheral component interface bus of the host computer. When the driver program receives, from an application program running on the host computer a storage access command in accordance with the protocol, specifying a storage transaction, a remote direct memory access (RDMA) operation is performed by a network interface controller (NIC) connected to the host computer so as to execute the storage transaction via a network on a remote storage device.

    摘要： 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.

    摘要： A method for computing includes running a plurality of virtual machines on a computer having one or more cores and a memory. Upon occurrence of an event pertaining to a given virtual machine during a period in which the given virtual machine is unable to receive an interrupt, an interrupt message is written to a pre-assigned interrupt address in the memory. When the given virtual machine is able to receive the interrupt, after writing of the interrupt message, a context of the given virtual machine is copied from the memory to a given core on which the given virtual machine is running, and a hardware interrupt is automatically raised on the given core responsively to the interrupt message in the memory.
