Abstract: Described herein is a graphics processor having processing resources with configurable thread and register configurations. Program code can configure a number of registers and accumulators that will be used by hardware threads during execution of the program code by the graphics processor. Processing resources within the graphics processor can be configured to assign different numbers of registers and accumulators to hardware threads based on the configuration requested by program code to be executed by the processing resource.

Abstract: Methods and apparatus relating to techniques for improved SIMD channel utilization in a divergent control flow environment. In an example, an apparatus comprises logic, at least partially comprising hardware logic, to determine instructions in an instruction set which are combinable into a super-instruction to execute in a divergent control flow environment, combine a first instruction and a second instruction to form a super-instruction, encode the super-instruction, and queue the super-instruction for execution on a processor. Other embodiments are also disclosed and claimed.
