Techniques for arbitrating and scheduling thread usage in multi-threaded compute engines. Various schemes are disclosed for allocating compute (execution) usage of compute engines supporting multiple hardware contexts. The schemes include non-pre-emptive (cooperative) round-robin, priority-based round-robin with pre-emption, time division, cooperative round-robin with time division, and priority-based round-robin with pre-emption and time division. Aspects of the foregoing schemes may also be combined to form new schemes. The schemes enable finer control of thread execution in pipeline execution environments, such as employed for performing packet-processing operations.
