Abstract: In one embodiment, the present invention includes a processor that can generate data packets for transmission to an agent, where the processor can generate a data packet having a command portion including a first operation code to encode a transaction type for the data packet and a second operation code to encode a processor-specific operation. This second operation code can encode many different features such as an indication that the data packet is of a smaller size than a standard packet, in order to reduce bandwidth. This operation code can also identify an operation to be performed by a destination agent coupled to the agent. Other embodiments are described and claimed.

Abstract: Methods and apparatus relating to ring protocols and techniques are described. In one embodiment, a first agent generates a request to write to a cache line of a cache over a first ring of a computing platform. A second agent that receives the write request forwards it to a third agent over the first ring of the computing platform. In turn, a third agent (e.g., a home agent) receives data corresponding to the write request over a second, different ring of the computing platform and writes the data to the cache. Other embodiments are also disclosed.

Abstract: Apparatus, systems, and methods provide dynamic spatial power steering among a plurality of power domains in the computer system on a per phase basis of a particular application. Dynamic spatial power steering may include, for example, determining a plurality of phases corresponding to an application comprising tasks for execution on a processing node. determining a spatial power distribution between a plurality of power domains on the processing node based on a performance metric for each phase, monitoring the application to detect a current phase, and applying the spatial power distribution correspond to the current phase to the plurality of power domains.
