Abstract: A mechanism is described for facilitating dynamic and remote memory collaboration at computing devices according to one embodiment of the invention. A method of embodiments of the invention includes dynamically classifying a computing device of a plurality of computing devices as a memory server, where the plurality of computing devices are coupled to each other over a network. The method may further include offering, by the memory server, of memory to be used by one or more of the plurality of computing devices classified as one or more memory clients, and remotely granting, by the memory server, of the memory to the one or more memory clients.

Abstract: 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).

Abstract: Techniques are described for determining a temporary latency tolerance report (tLTR) value. A processing unit has to respond to a device interrupt within a duration specified by tLTR to ensure no incoming data is lost due to device buffer overflow. The tLTR value can be used to prevent the processing unit from entering too deep a sleep state when a device driver anticipates multiple sequential interrupts for a transaction.

Abstract: 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.

Abstract: Generally this disclosure describes methods and systems for conserving energy in a client platform by maintaining connectivity between the client platform and a remote resource when the client is in a low-power state.

Abstract: A method and apparatus for managing core affinity for network packet processing is provided. Low-power idle state of a plurality of processing units in a system including the plurality of processing units is monitored. Network packet processing is dynamically reassigned to processing units that are in a non-low power idle state to increase the low-power idle state residency for processing units that are in a low-power idle state resulting in reduced energy consumption.

Abstract: An embodiment may include circuitry to be comprised in a node. The node may be communicatively coupled to a network and may include a host processor to execute at least one communication protocol-related process. The circuitry may determine, at least in part, whether to buffer, at least in part, at least one packet received from the network based at least in part upon whether a weighted moving average exceeds a first threshold and is less than a second threshold. The average may be determined based at least in part upon one or more time intervals between one or more packet receptions from the network. Many alternatives, variations, and modifications are possible.

Abstract: In general, in one aspect, a method includes determining a repeated, periodic DMA (Direct Memory Access) coalescing interval based, at least in part, on a power sleep state of a host platform. The method also includes buffering data received at the device in a FIFO (First-In-First-Out) queue during the interval and DMA-ing the data enqueued in the FIFO to a memory external to the device after expiration of the repeated, periodic DMA coalescing interval.

Abstract: A computer system may comprise a platform in which a processing block may be provisioned. The processing block may determine an optimal compression ratio such that the optimal compression ratio may cause a minimum of a total power to be consumed by the computer platform.

The processing block may generate compressed frames from a plurality of frames generated by an application. The compressed frames may be generated by encoding the plurality of frames using the optimal compression ratio. The processing block may select a network interface from multiple network interfaces supported by the computer system to transmit the compressed frames.
