Abstract: Disclosed embodiments relate to spatial and temporal merging of remote atomic operations. In one example, a system includes an RAO instruction queue stored in a memory and having entries grouped by destination cache line, each entry to enqueue an RAO instruction including an opcode, a destination identifier, and source data, optimization circuitry to receive an incoming RAO instruction, scan the RAO instruction queue to detect a matching enqueued RAO instruction identifying a same destination cache line as the incoming RAO instruction, the optimization circuitry further to, responsive to no matching enqueued RAO instruction being detected, enqueue the incoming RAO instruction; and, responsive to a matching enqueued RAO instruction being detected, determine whether the incoming and matching RAO instructions have a same opcode to non-overlapping cache line elements, and, if so, spatially combine the incoming and matching RAO instructions by enqueuing both RAO instructions in a same group of cache line queue entries at different offsets.

Abstract: Examples include a method of switching a packet by a virtual switch by receiving a system call to transmit a packet from a first application running in a first container on a first core, determining a destination for the packet, obtaining a buffer in an application memory space of the destination, copying the packet to the destination application memory space, and writing an entry for the packet to a queue assigned to the destination, the destination queue being in a queue manager. The packet may then be obtained by an entity at the destination.

Abstract: Aspects of data re-direction are described, which can include software-defined networking (SDN) data re-direction operations. Some aspects include data re-direction operations performed by one or more virtualized network functions. In some aspects, a network router decodes an indication of a handover of a user equipment (UE) from a first end point (EP) to a second EP, based on the indication, the router can update a relocation table including the UE identifier, an identifier of the first EP, and an identifier of the second EP. The router can receive a data packet for the UE, configured for transmission to the first EP, and modify the data packet, based on the relocation table, for rerouting to the second EP. In some aspects, the router can decode handover prediction information, including an indication of a predicted future geographic location of the UE, and update the relocation table based on the handover prediction information.

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: Apparatus and methods implementing a hardware queue management device for reducing inter-core data transfer overhead by offloading request management and data coherency tasks from the CPU cores. The apparatus include multi-core processors, a shared L3 or last-level cache (“LLC”), and a hardware queue management device to receive, store, and process inter-core data transfer requests. The hardware queue management device further comprises a resource management system to control the rate in which the cores may submit requests to reduce core stalls and dropped requests. Additionally, software instructions are introduced to optimize communication between the cores and the queue management device.

Abstract: Technologies for inflight packet count limiting include a network device. The network device is to receive a packet from a producer application. The packet is configured to be enqueued into a packet queue as a queue element to be consumed by a consumer application. The network device is also to increment, in response to receipt of the packet, an inflight count variable, determine whether a value of the inflight count variable satisfies an inflight count limit, and enqueue, in response to a determination that the value of the inflight count variable satisfies the inflight count limit, the packet.
