Abstract: Systems, apparatuses, and methods for performing split-workgroup dispatch to multiple compute units are disclosed. A system includes at least a plurality of compute units, control logic, and a dispatch unit. The control logic monitors resource contention among the plurality of compute units and calculates a load-rating for each compute unit based on the resource contention. The dispatch unit receives workgroups for dispatch and determines how to dispatch workgroups to the plurality of compute units based on the calculated load-ratings. If a workgroup is unable to fit in a single compute unit based on the currently available resources of the compute units, the dispatch unit divides the workgroup into its individual wavefronts and dispatches wavefronts of the workgroup to different compute units. The dispatch unit determines how to dispatch the wavefronts to specific ones of the compute units based on the calculated load-ratings.
