Abstract: A system includes multiple processors to communicate with one another via one or more network devices. One or more of the processors are to specify, for a given type of a collective operation to be executed by the system, a packet-processing configuration to be applied by the network devices in processing packets relating to collective operations of the given type, and, during execution of a collective operation of the given type, to mark the packets relating to the collective operation with a mark indicative of the packet-processing configuration, thereby instructing one or more of the network devices to process the packets relating to the collective operation, responsively to the mark, in accordance with the packet-processing configuration.

Abstract: In one embodiment, a system for managing cloud infrastructure performance for cyclical workloads processed in a cloud infrastructure includes one or more processor to receive values of a period metric of the cyclical workloads based on data collected by network devices in the cloud infrastructure, and adjust at least one network device management parameter of at least one of the network devices based on the period metric values causing changes to the processing of the cyclical workloads in the cloud infrastructure, and memory to store data used by the at least one processor.

Abstract: A device, communication system, and method are provided. In one example, a system for routing traffic is described that includes circuits to receive a plurality of packets associated with a destination, determine a plurality of bins based on the destination of the packets, wherein each bin of the plurality of bins is associated with a respective port of the plurality of ports, and, for each packet of the plurality of packets, select a bin of the plurality of bins and forward the packet via the port associated with the selected bin. Described circuits also receive an adaptive routing notification packet via a first port associated with a first bin and in response associate the first bin with a second port and de-associate the first bin with the first port.

Abstract: A heaterless hollow cathode provides electron emission current in an electric space propulsion system. A mechanical, thermal, and electromagnetic design of the cathode apparatus is presented, and a method of operation for rapid ignition and stabilization of the cathode is provided. The keeper of the cathode apparatus has a thickness change which reduces the flow of heat away from the cathode's emitter assembly. The method for heating the emitter assembly includes controlling applied voltages so that the current flowing from the emitter assembly to the keeper is maintained at a predetermined fixed value. By this method, damage to the electron emitting surfaces of the emitter assembly by electric arcing and/or by depletion of dopant materials is avoided.
