摘要
用户提交的作业请求在网格作业处理环境中将被封装成作业对象,并依次被解析、调度、资源选择和提交。设计并实现了一种基于链队列的新型网格作业处理环境,由预处理队列、调度队列、资源选择队列和提交队列构成的一个链队列结构采用多线程技术,将作业处理流程划分成若干阶段,由控制中心统一管理作业对象在链队列中的操作。
The job request submitted by users is turned to a job object in the grid job handling envi- ronment, which is subjected to four steps in turn： parsing, scheduling, resources selecting and sub- mitting. This paper designs and implements a new type of environment to deal with grid job based on a chain-queue structure. The structure consists of prehandling-queue, scheduling-queue, resource selecting-queue and submitting-queue which adopts multithread technique. The whole process is di- vided into several steps and the job control center manages the job＇s actions in the chain-queue.
