    Abstract: An apparatus is provided that includes a network interface to transmit and receive data packets over a network; a memory including one or more buffers; an arithmetic logic unit to perform arithmetic operations for organizing and combining the data packets; and a circuitry to receive, via the network interface, data packets from the network; aggregate, via the arithmetic logic unit, the received data packets in the one or more buffers at a network rate; and transmit, via the network interface, the aggregated data packets to one or more compute nodes in the network, thereby optimizing latency incurred in combining the received data packets and transmitting the aggregated data packets, and hence accelerating a bulk data allreduce operation. One embodiment provides a system and method for performing the allreduce operation. During operation, the system performs the allreduce operation by pacing network operations for enhancing performance of the allreduce operation.

    Abstract: Systems and methods are described for providing per traffic class routing of data within a network. A network switch has the capability to classify traffic data based on High Performance Computing (HPC) related characteristics. Traffic classes are defined based on aspects of HPC, such as routing, ordering, redirection, quiesce, HPC protocol configuration, and telemetry. A switch can receive packets at an ingress port of a switch fabric, and determine traffic classifications for the packets. The traffic classification is selected from a group of defined traffic classes. Then, the switch can generate a fabric specific flag for the at least one packet that indicates the determined traffic classification, where the fabric specific flag is used for routing packets based on their assigned traffic classification. Examples of traffic classes include: low latency class; dedicated access class; bulk data class; best efforts class; and scavenger class.

    Abstract: Systems and methods of routing a data communication across a network having a plurality switches are provided by monitoring the operation of the plurality of global links to determine which of the plurality of global links provide working paths. A routing table indicative of a status for the plurality of links is maintained, where the routing table provides weighting for each of the working paths. When routing, a link using a weighted pseudo-random selection from the choices available in the routing table is selected. Routing along one of the working paths commensurate with the selected link is performed, and the weighting is updated based upon the operation of the plurality of links.

    IPC: G06F13/16

    Abstract: A network interface controller (NIC) capable of efficient event management is provided. The NIC can be equipped with a host interface, a first memory device, and an event management module. During operation, the host interface can couple the NIC to a host device. The event management module can identify an event associated with an event queue stored in a second memory device of the host device. The event management module can insert, into a buffer, an event notification associated with the event. The buffer can be associated with the event queue and stored in the first memory device. If the buffer has met a release criterion, the event management module can insert, via the host interface, the aggregated event notifications into the event queue.
