摘要： Methods and systems may provide for executing, by a physically distributed set of compute slices, a plurality of work items. Additionally, the coherency of one or more memory lines associated with the plurality of work items may be maintained, by a cache fabric, across a graphics processor, a system memory and one or more host processors. In one example, a plurality of crossbar nodes track the one or more memory lines, wherein the coherency of the one or more memory lines is maintained across a plurality of level one (L1) caches and a physically distributed cache structure. Each L1 cache may be dedicated to an execution block of a compute slice and each crossbar node may be dedicated to a compute slice.

摘要： In one embodiment, a processor includes: a graphics processor to execute a workload; and a power controller coupled to the graphics processor. The power controller may include a voltage ramp circuit to receive a request for the graphics processor to operate at a first performance state having a first operating voltage and a first operating frequency and cause an output voltage of a voltage regulator to increase to the first operating voltage. The voltage ramp circuit may be configured to enable the graphics processor to execute the workload at an interim performance state having an interim operating voltage and an interim operating frequency when the output voltage reaches a minimum operating voltage. Other embodiments are described and claimed.
