摘要： Systems and Methods for task allocation in a multiprocessor environment employing power management techniques are described wherein tasks are allocated relative to the density given by the ratio of worst-case-execution time and deadline of a task and also the harmonicity of a task's period with respect to a task-set. Tasks are allocated to a given processor based on either minimum density or maximum harmonicity depending on which allocation results in a lower clock frequency. Assigning a task to the processor with lowest density results in balancing the density across processors while assigning task to the processor with maximum harmonicity attempts to maximize the utilization of the processor.

摘要： A multi processor task allocation method is described that considers task dependencies while performing task allocation in order to avoid blocking of a task's execution while waiting for the resolution of the dependency. While allocating the tasks to the processors the potential blocking time is considered, and the best allocation that will have the least amount of blocking time is found.
