    摘要: Technologies for managing network flow lookups of a network device include a network controller and a target device, each communicatively coupled to the network device. The network device includes a cache for a processor of the network device and a main memory. The network device additionally includes a multi-level hash table having a first-level hash table stored in the cache of the network device and a second-level hash table stored in the main memory of the network device. The network device is configured to determine whether to store a network flow hash corresponding to a network flow indicating the target device in the first-level or second-level hash table based on a priority of the network flow provided to the network device by the network controller.

    摘要: Processors and methods implementing a machine instruction to perform cache line demotion on multiple cache lines to enable efficient sharing of cache lines between processor cores. One general aspect includes a processor comprising: a plurality of hardware processor cores, where each of the hardware processor cores to include a first cache. The processor also includes a second cache, communicatively coupled to and shared by the plurality of hardware processor cores. The processor to support a first machine instruction, the first machine instruction to include a vector register operand identifying a vector register which contains a plurality of data elements each used to identify a cache line. An execution of the first machine instruction by one of the plurality of hardware processor cores to cause a plurality of identified cache lines to be demoted, such that the demoted cache lines are moved from the first cache to the second cache.

    摘要: Technologies for packet flow classification on a computing device include a hash table including a plurality of hash table buckets in which each hash table bucket maps a plurality of keys to corresponding traffic flows. The computing device performs packet flow classification on received data packets, where the packet flow classification includes a plurality of sequential classification stages and fetch classification operations and non-fetch classification operations are performed in each classification stage. The fetch classification operations include to prefetch a key of a first received data packet based on a set of packet fields of the first received data packet for use during a subsequent classification stage, prefetch a hash table bucket from the hash table based on a key signature of the prefetched key for use during another subsequent classification stage, and prefetch a traffic flow to be applied to the first received data packet based on the prefetched hash table bucket and the prefetched key. The computing device handles processing of received data packets such that a fetch classification operation is performed by the flow classification module on the first received data packet while a non-fetch classification operation is performed by the flow classification module on a second received data packet.
