Abstract: An energy-efficient assignment of a task set T to a group of M processing devices models the process of deciding the assignment as a combinatorial optimization problem having an objective function optimizing the power consumption of the devices when executing subsets of the tasks, under a constraint that the total utilization of the task subset assigned to each respective processing device is lower than a threshold depending on the number of its processor cores. The objective function may be: min ?i=1M Pi(?i), where ?i denotes the subset of tasks allocated to the ith device, and Pi(?i) represents power consumption of the ith device when executing ?i, and the constraint U?i?Mi/4 for all the devices, where U?i is the total utilization of ?i executing on the ith device, and Mi denotes the number of cores of the ith device. Solving the problem using a MaxMin or genetic algorithm gives good energy efficiency.

Abstract: According to a directed-acyclic-graph representation, each real-time task is decomposed into sub-tasks, and a timing diagram is generated representing execution of the sub-tasks on a schedule respecting their deadlines and dependencies assuming an infinite number of processor cores. The timing diagram is segmented based on sub-task release times and deadlines, and each segment includes one or more parallel threads. For each segment, dependent on its workload, the frequency and/or voltage is selected to be used by the processor node(s) that are to execute the one or more threads of the segment, so as to reduce power consumption consistent with respecting the sub-task deadlines. Execution of the sub-tasks of the segments is then scheduled assuming the processor-core frequencies and/or voltages set in the deciding step, preferably by a global earliest deadline first algorithm.
