运用蒙特卡洛模拟法的数据流调度优化模型研究
Research on Data Flow Scheduling Optimization Model Based on Monte Carlo Simulation
摘要
Abstract
The task execution time of the traditional static data flow task scheduling method is predictable. But in the re-al-time flow computing platform,the order of the data flow and the size of the data are uncertain,leading to the task execution time is uncertain.This paper presents a data flow task scheduling method based on Monte Carlo simulation method.This method gener-ates a large amount of task execution time under a certain constraint condition by using a random number generation algorithm,and generates a corresponding precondition by the classical static scheduling algorithm(HEFT). Finally,an optimal pre-scheduling scheme is obtained through comprehensive comparison.The experimental results show that the method proposed in this paper not on-ly greatly shortens the task scheduling time,but also has a very strong universality.关键词
