Abstract: An apparatus, such as a graphical processing unit (GPU), includes one or more processors configured to determine a plurality of first locality information of a received wave at a processing unit and to select a first processing element of a plurality of processing elements, the first processing unit having a plurality of second locality information from a previous wave that matches the plurality of first locality information to execute the received wave.

Abstract: Systems, methods, and techniques dynamically utilize load balancing for workgroup assignments between a group of shader engines by a command processor of a graphics processing unit (GPU). Based on one or more commands received for execution, a plurality of workgroups is generated for assignment to a plurality of shader engines for processing, each shader engine including a respective quantity of active compute units. Each workgroup of the plurality of workgroups is dynamically assigned to a respective shader engine for execution based at least in part on indications of available resources respectively associated with each of the shader engines. In various embodiments, the indications of available resources may include physical parameters regarding each shader engine, as well as current status information regarding the processing of workgroups assigned to each shader engine.

Abstract: Parallel processors typically allocate resources to workloads based on workload priority. Priority inversion of resource allocation between workloads of different priorities reduces the operating efficiency of a parallel processor in some cases. A parallel processor mitigates priority inversion by soft-locking resources to prevent their allocation for the processing of lower priority workloads. Soft-locking is enabled responsive to a soft-lock condition, such as one or more priority inversion heuristics exceeding corresponding thresholds or multiple failed allocations of higher priority workloads within a time period. In some cases, priority inversion heuristics include quantities of higher priority workloads and lower priority workloads that are in-flight or incoming, ratios between such quantities, quantities of render targets, or a combination of these.
