基于计算特征的分布式空三计算任务调度研究
摘要
Abstract
Starting with the present situation of oblique photo grammetry,this paper sorts out the calculation flow of the mainstream spatial three algorithms,through the analysis of its algorithm characteristics,based on the hardware resources used in the computing process,in order to improve the efficiency of task scheduling in the computing process,a distributed spatial three computing task scheduling rule based on computing features is designed.A series of comparative experiments are carried out according to the designed scheduling rules.The experimental results show that on the computing nodes with gradient distribution,the scheduling method using distributed spatial three computing task scheduling rules based on computing features is compared with that without scheduling rules.Since the high-performance host has a higher priority in task delivery,hence the higher turnover of the task package.The distributed cluster using scheduling rules performs better in computing time,and has a certain reference significance in the direction and means of improving the efficiency of empty three computing.关键词
