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.
