Abstract: Apparatus, method, and system for implementing a software-transparent hardware predictor for core-to-core data communication optimization are described herein. An embodiment of the apparatus includes a plurality of hardware processor cores each including a private cache; a shared cache that is communicatively coupled to and shared by the plurality of hardware processor cores; and a predictor circuit. The predictor circuit is to track activities relating to a plurality of monitored cache lines in the private cache of a producer hardware processor core (producer core) and to enable a cache line push operation upon determining a target hardware processor core (target core) based on the tracked activities. An execution of the cache line push operation is to cause a plurality of unmonitored cache lines in the private cache of the producer core to be moved to the private cache of the target core.

Abstract: A central processing unit can offload table lookup or tree traversal to an offload engine. The offload engine can provide hardware accelerated operations such as instruction queueing, bit masking, hashing functions, data comparisons, a results queue, and a progress tracking. The offload engine can be associated with a last level cache. In the case of a hash table lookup, the offload engine can apply a hashing function to a key to generate a signature, apply a comparator to compare signatures against the generated signature, retrieve a key associated with the signature, and apply the comparator to compare the key against the retrieved key. Accordingly, a data pointer associated with the key can be provided in the result queue. Acceleration of operations in tree traversal and tuple search can also occur.

Abstract: Methods and apparatus for facilitating efficient Quality of Service (QoS) support for software-based packet processing by offloading QoS rate-limiting to NIC hardware. Software-based packet processing is performed on packet flows received at a compute platform, such as a general purpose server, and/or packet flows generated by local applications running on the compute platform. The packet processing includes packet classification that associates packets with packet flows using flow IDs, and identifying a QoS class for the packet and packet flow. NIC Tx queues are dynamically configured or pre-configured to effect rate limiting for forwarding packets enqueued in the NIC Tx queues. New packet flows are detected, and mapping data is created to map flow IDs associated with flows to the NIC Tx queues used to forward the packets associated with the flows.

Abstract: Methods and apparatus to support multiple-writer/multiple-reader concurrency for software flow/packet classification on general purpose multi-core systems. A flow table with rows mapped to respective hash buckets with multiple entry slots is implemented in memory of a host platform with multiple cores, with each bucket being associated with a version counter. Multiple writer and reader threads are run on the cores, with writers providing updates to the flow table data. In connection with inserting new key data, a determination is made to which buckets will be changed, and access rights to those buckets are acquired prior to making any changes. For example, under a flow table employing cuckoo hashing, access rights are acquired to buckets along a full cuckoo path.

Abstract: Technologies for flow rule aware exact match cache compression include multiple computing devices in communication over a network. A computing device reads a network packet from a network port and extracts one or more key fields from the packet to generate a lookup key. The key fields are identified by a key field specification of an exact match flow cache. The computing device may dynamically configure the key field specification based on an active flow rule set. The computing device may compress the key field specification to match a union of non-wildcard fields of the active flow rule set. The computing device may expand the key field specification in response to insertion of a new flow rule. The computing device looks up the lookup key in the exact match flow cache and, if a match is found, applies the corresponding action. Other embodiments are described and claimed.

Abstract: Technologies for efficient network flow classification include a computing device that receives a network packet that includes a header. The computing device generates a vector Bloom filter (VBF) key as a function of the header and searches multiple VBFs for a VBF that matches the VBF key. Each VBF is associated with a flow sub-table that includes one or more flow rules. Each flow sub-table is associated with a mask length. If a matching VBF is found, the computing device searches the corresponding flow sub-table for a flow rule that matches a masked header of the network packet. If no matching VBF is found or if no matching flow rule is found, the computing device searches all of the flow sub-tables for a flow rule that matches the header. The computing device applies a flow action of a matching flow rule. Other embodiments are described and claimed.
