Abstract
Briefly, methods and apparatus to rebalance workloads among processing cores utilizing a hybrid work donation and work stealing technique are disclosed that improve workload imbalances within processing devices such as, for example, GPUs. In one example, the methods and apparatus allow for workload distribution between a first processing core and a second processing core by providing queue elements from one or more workgroup queues associated with workgroups executing on the first processing core to a first donation queue that may also be associated with the workgroups executing on the first processing core. The method and apparatus also determine if a queue level of the first donation queue is beyond a threshold, and if so, steal one or more queue elements from a second donation queue associated with workgroups executing on the second processing core.
