一种自适应资源精细匹配的DAG调度方法
A DAG scheduling method for adaptive resources subtle matching
摘要
Abstract
For the task dependence of computing intensive or data intensive characteristics and the high coupling degree of parallel processing,a method of separating the execution sequence control of correlation task and processing logic of parallel al-gorithm is adopted. By means of the task decomposition approach and adaptive multi-resource subtle matching,the DEM data is used to establish the DAG task scheduling simulation of the large watershed eco-hydrology process with hundred-thousand magni-tude grids. The method performances of resolution,data scale,progress quantity and local resource manager(LRM)are evalua-ted under the condition of different resolutions by means of the multi-comparison method. The experimental results show that the DAG scheduling method of adaptive multi-resource subtle matching for task decomposition can improve the parallel performance and efficiency greatly,and has strong robustness and perfect scalability.关键词
