摘要： Systems and methods may provide for determining an absolute energy break-even time for a first low power state with respect to a current state of a system. A relative energy break-even time may also be determined for the first low power state with respect to a second low power state based on at least in part the absolute energy break-even time. In addition, an operating state may be selected for the system based on at least in part the relative energy break-even time.

摘要： The present disclosure provides techniques for cache management. A data block may be received from an IO interface. After receiving the data block, the occupancy level of a cache memory may be determined. The data block may be directed to a main memory if the occupancy level exceeds a threshold. The data block may be directed to a cache memory if the occupancy level is below a threshold.

摘要： An embodiment may include circuitry to determine whether to issue at least one credit to at least one sender of at least one packet. The credit(s) may be to grant permission to the at least one sender to issue the at least one packet to at least one receiver of the at least one packet. The determination of whether to issue the credit(s) may be based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the credit(s) is at least sufficient to provide at least a predetermined amount of reduction in power consumption. The relatively lower power state may be relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the credit(s). Additionally or alternatively, the circuitry may be to receive such credit(s).

摘要： Technologies for distributed table lookup via a distributed router includes an ingress computing node, an intermediate computing node, and an egress computing node. Each computing node of the distributed router includes a forwarding table to store a different set of network routing entries obtained from a routing table of the distributed router. The ingress computing node generates a hash key based on the destination address included in a received network packet. The hash key identifies the intermediate computing node of the distributed router that stores the forwarding table that includes a network routing entry corresponding to the destination address. The ingress computing node forwards the received network packet to the intermediate computing node for routing. The intermediate computing node receives the forwarded network packet, determines a destination address of the network packet, and determines the egress computing node for transmission of the network packet from the distributed router.
