Abstract
Systems and methods may provide for receiving a plurality of signals from a software module associated with a shared resource such as, for example, an unordered access view (UAV). The plurality of signals may include a first signal that indicates whether a draw call accesses the shared resource, a second signal that indicates whether a boundary of the draw call has been reached, and a third signal that indicates whether the draw call has a coherency requirement. Additionally, a workload corresponding to the draw call may be selectively dispatched in a shader invocation based on the plurality of signals.
