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.

Technologies for identifying a cache line of a network packet for eviction from an on-processor cache of a network device communicatively coupled to a network controller. The network device is configured to determine whether a cache line of the cache corresponding to the network packet is to be evicted from the cache based on a determination that the network packet is not needed subsequent to processing the network packet, and provide an indication that the cache line is to be evicted from the cache based on an eviction policy received from the network controller.

Methods and systems may provide for determining a next active window for a platform and notifying one or more of a plurality of devices of the platform of the next active window being determined. Additionally, one or more of the plurality of devices may be notified of an onset of the next active window. In one example, a pre-warm message is issued to notify one or more of the plurality of devices of the next active window being determined.
摘要:
A method and apparatus for selectively parking routers used for routing traffic in mesh interconnects. Various router parking (RP) algorithms are disclosed, including an aggressive RP algorithm where a minimum number of routers are kept active to ensure adequate network connectivity between active nodes and/or intercommunicating nodes, leading to a maximum reduction in static power consumption, and a conservative RP algorithm that favors network latency considerations over static power consumption while also reducing power. An adaptive RP algorithm is also disclosed that implements aspects of the aggressive and conservative RP algorithms to balance power consumption and latency considerations in response to ongoing node utilization and associated traffic. The techniques may be implemented in internal network structures, such as for single chip computers, as well as external network structures, such as computing clusters and massively parallel computer architectures. Performance modeling has demonstrated substantial power reduction may be obtained using the router parking techniques while maintaining Quality of Service performance objectives.
摘要:
Devices and methods for optimizing semi-active workloads are described herein. A network interface device may be configured to offload data packet acknowledgment responsibilities of a host platform by transmitting, to the sender of the packets, acknowledgements of packets received throughout a time duration. Upon completion of the time duration, the network interface device may trigger the host platform to perform batch processing of the data packets received during the time duration.

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.

Embodiments of an apparatus, system and method are described for input/output (I/O) device assisted platform power management. An apparatus may comprise, for example, power management logic operative to receive idle duration information from one or more input/output (I/O) devices and to modify a power state for one or more components based on the idle information. Other embodiments are described and claimed.
摘要:
Technologies for supporting concurrency of a flow lookup table at a network device. The flow lookup table includes a plurality of candidate buckets that each includes one or more entries. The network device includes a flow lookup table write module configured to perform a displacement operation of a key/value pair to move the key/value pair from one bucket to another bucket via an atomic instruction and increment a version counter associated with the buckets affected by the displacement operation. The network device additionally includes a flow lookup table read module to check the version counters during a lookup operation on the flow lookup table to determine whether a displacement operation is affecting the presently read value of the buckets. Other embodiments are described herein and claimed.
