Abstract: A method includes providing a plurality of processes interconnected by a network, each of the plurality of processes being configured to hold a block of data destined for others of the plurality of processes. A set of data for all-to-all data exchange is received from one or more of the processes. The set of data is configured as a plurality of blocks of data in a matrix as matrix data, the matrix being distributed among the plurality of processes. The matrix data is transposed by changing the position of selected blocks of data of the plurality of blocks of data relative to the other blocks of data of the plurality of the blocks of data, without changing the structure of each of the blocks of data. The transposed matrix data is over the network and is then received, repacked, and conveyed to destination processes.

Abstract: A network interface device includes a local register and packet processing circuitry coupled to the local register. The packet processing circuitry is to: capture a network packet transmitted by a software application running on an integrated computing system; capture, at time of transmission of the network packet, a value of a physical clock as a receive timestamp for subscriber entities that are running on the integrated computing system; store the receive timestamp in the local register; associate the receive timestamp from the local register with a first packet copy of the network packet; insert the first packet copy to a first receive pipeline of a first subscriber entity; associate the receive timestamp from the local register with a second packet copy of the network packet; and insert the second packet copy to a second receive pipeline of a second subscriber entity.

Abstract: A method for collective communications includes invoking a collective operation over a group of computing processes in which the processes in the group concurrently transmit and receive data messages to and from other processes in the group via a communication medium. The processes detect respective sizes of the data messages and transmit the data messages for which the respective sizes are greater than a predefined threshold to respective destination processes in the group without aggregation. The data messages for which the respective sizes are less than the predefined threshold are aggregated, and the aggregated data messages are transmitted to the respective destination processes.

Abstract: A networking device and system are described, among other things. An illustrative system is disclosed to include a shared buffer and at least a flow controller. In some embodiments, the system and/or flow controller may be configured to measure a packet flow's bandwidth consumption of the shared buffer, assign a flow-type attribute to the packet flow based on the packet flow's bandwidth consumption of the shared buffer, select a shared buffer schema for the packet flow based on the flow-type attribute assigned to the packet flow, and apply the selected shared buffer schema to the packet flow. For example, the flow-type attribute assigned to the packet flow may comprise a mice flow state or an elephant flow state, and a reserve attribute may be assigned to the flow based on the packet flow being assigned the mice flow state or the elephant flow state.

Abstract: A network device includes multiple ports, a Shared Buffer (SB) and a SB controller. The ports to connect to a communication network. The SB to temporarily store packets received from the communication network via the ports, the packets belonging to multiple flows. The SB controller to allocate one or more flow-specific storage regions in the SB, a given flow-specific storage region being allocated to store the packets that (i) belong to respective one or more of the flows and (ii) are to be transmitted via a respective egress queue. In response to detecting that an occupancy level in the given flow-specific storage region exceeds a specified occupancy threshold, the SB controller to report the flows in the given flow-specific storage region as congested.

Abstract: Technologies for chip-to-chip (C2C) yield and performance optimization in a die stacking platform are described. One apparatus includes a substrate, a first integrated circuit disposed on the substrate at a first location, a second integrated circuit disposed on the substrate at a second location, and a third integrated circuit disposed on the second integrated circuit. The second integrated circuit is coupled to the first integrated circuit using a first chip-to-chip (C2C) interface via a physical terminal. The third integrated circuit is coupled to the first integrated circuit using a second C2C interface via the physical terminal. Only one of the first C2C interface and the second C2C interface is active at a time.

Abstract: A network element includes one or more ports and a packet processor. The one or more ports are to transmit and receive packets over a network. The packet processor is to apply a plurality of rules to the packets, each rule specifying (i) expected values for each header field of a group of header fields of the packets, including, for a given header field in the group, at least a set of multiple expected values, (ii) a group ID associated with the set, and (iii) an action to be applied to the packets whose header fields match the expected values.
