    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： Methods and apparatus for provision of adaptive packet deflection to achieve fair, low-cost, and/or energy-efficient Quality of Service (QoS) in Network-on-Chip (NoC) devices are described. In some embodiments, it is determined whether a target port of a packet has reached a threshold utilization value and the packet is routed to an alternate port in response to a deflection probability value that is to be determined based on a utilization value of the target port and a priority level value of the packet. Other embodiments are also claimed and/or disclosed.

    摘要： The present invention may provide a computer system including a plurality of tiles divided into multiple virtual domains. Each tile may include a router to communicate with others of said tiles, a private cache to store data, and a spill table to record pointers for data evicted from the private cache to a remote host, wherein the remote host and the respective tile are provided in the same virtual domain. The spill tables may allow for faster retrieval of previously evicted data because the home registry does not need to be referenced if requested data is listed in the spill table. Therefore, embodiments of the present invention may provide a distance-aware cache collaboration architecture without incurring extraneous overhead expenses.

    摘要： An embodiment may include network controller to be comprised in a first node. The node may be communicatively coupled to a network and may include a host processor to execute an operating system environment. The operating system environment may include, at least in part, a communication protocol stack and an application. The circuitry may receive, at least in part, a packet from the network. The packet may include, at least in part, a header and payload. At least one portion of the payload may be associated with the application. The circuitry may issue at least one portion of the header to the stack. The circuitry may issue the at least one portion of the payload to a destination device in a manner that by-passes involvement of the stack. The destination device may be specified, at least in part, by the application. Many alternatives, variations, and modifications are possible.
