The invention discloses a power adaptive task scheduling method and a system. The method comprises the following steps of: obtaining current task information; dividing and counting the task information according to the big data programming model MapReduce to obtain a plurality of sub-tasks which can run in parallel; acquiring a fluctuation state of the output power and a state of a task load, andobtaining state information; adjusting the number and type of cores of the processor according to the state information; the subtasks being dispatched to the worker threads according to the processorafter adjusting the audits and types. The method or system can solve the problems of interruption of task execution and low efficiency caused by uncertainty of processor working power requirement andoutput power of energy collection unit in the task scheduling process of current energy collection system.
Description
technical field [0001] The invention relates to the field of task scheduling, in particular to a power adaptive task scheduling method and system. Background technique [0002] In recent years, the Internet of Things technology has developed by leaps and bounds, and high performance and low power consumption have become an important development trend of Internet of Things devices. The demand for high performance means the improvement of system energy consumption, but the current development speed of batteries has lagged far behind the growth of energy consumption demand, and battery power supply still has the problems of large volume, weight and high maintenance costs. It is an effective way to solve energy problems by adopting new energy harvesting technology to convert various environmental energies (such as sunlight, wind, tide and vibration, etc.) However, due to the intermittent, random, and uncertain characteristics of external environmental resources, the output powe...
