Abstract: A network device, a network interface controller, and a switch are provided. In one example, a shared buffer includes a plurality of cells of memory, one or more ports read data from the shared buffer and write data to the shared buffer, and a controller circuit selectively enables and disables cells of memory of the shared buffer based on an amount of data stored in the shared buffer. Power consumption of the shared buffer is in proportion to a number of enabled cells of memory.

Abstract: A device includes a receiver including a timestamp generator to update timestamps at a first rate. The receiver is to estimate a first time for receiving a signal, wherein the signal is associated with a synchronization operation. The receiver is further to receive the signal at a second time. The receiver is further to determine a difference between the second time and the first time, wherein the difference is associated with an error of the timestamp generator of the receiver. The receiver can also adjust the first rate to a second rate at which to update the timestamps by the timestamp generator, responsive to determining the difference between the first time and the second time.

Abstract: A network device includes a first interface, a second interface, and circuitry. The first interface is configured to communicate at least with a memory. The second interface is configured to communicate over a network with a peer network device. The circuitry is configured to receive a request to transfer data over the network between the memory and the peer network device in accordance with (i) a pattern of offsets to be accessed in the memory and (ii) a memory key representing a memory space to be accessed using the pattern, and to transfer the data in accordance with the request.

Abstract: Methods, systems, and computer program products to generate a telemetry pipeline. In embodiments, the system includes a communication interface that receives one or more user-defined functions for the telemetry pipeline. The system also includes control logic that implements programmatically the one or more user-defined functions to collect telemetry data at a plurality of layers in the telemetry pipeline based on the one or more user-defined functions and calculate smart metrics at different layers of the plurality of layers in the telemetry pipeline. The smart metrics may be calculated at a layer closest to where associated telemetry data is collected.

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 device, system-on-a-chip, and method of performing an auto-negotiation for a planarized computing system. In response to a link request, switching hardware determines whether a source of the link request is planarized or non-planarized. If a mismatch between a received link request and a sent link request occurs, a lower-level event is escalated to the operating system which is enabled to respond to continue the auto-negotiation process.
