    Abstract: One embodiment provides for a general-purpose graphics processing unit multiple processing elements having a single instruction, multiple thread (SIMT) architecture configured to perform hardware multithreading during execution of a plurality of thread groups. The plurality of thread groups can include one or more sub-groups of threads, with a first sub-group is associated with a first thread group and a second sub-group associated with a second thread group. Data dependencies can be used to trigger the launch of threads, such that when a first thread in the second sub-group has a data dependency upon a first thread in the first sub-group, circuitry in the general-purpose graphics processing unit can launch at least the first thread in the second sub-group to execute in response to satisfaction of the data dependency.

    Abstract: One embodiment provides for a general-purpose graphics processing unit multiple processing elements having a single instruction, multiple thread (SIMT) architecture, the multiple processing elements to perform hardware multithreading during execution of multiple warps of threads, wherein a warp is a group of parallel threads; a scheduler to schedule a set of sub-warps to the multiple processing elements at sub-warp granularity, wherein a sub-warp is a sub-group of parallel threads, a warp includes multiple sub-warps, and the scheduler is to schedule threads in a first sub-warp of a first warp of threads to execute concurrently with the threads in a second sub-warp of a second warp of threads; and a logic unit including hardware or firmware logic, the logic unit to group active threads for execution on the multiple processing elements.
