SYSTEMS AND METHODS OF TASK ALLOCATION IN A MULTIPROCESSING ENVIRONMENT HAVING POWER MANAGEMENT |
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.
