A new static scheduling algorithm based on job network dag module is present to balance network workload statically as the partner of the dynamic load balancing mechanism 根据作业网络,提出了一个基于作业网络dag模型的静态调度算法,该算法是对动态负载平衡算法的扩展,用于作业网络的静态负载平衡。
The platform independent jobnetwork script can construct unit jobs to a job network according to the dependency of these jobs . and this job network can be submitted and controlled by jms as a whole 作业网络是对作业概念的扩展,通过跨平台作业网络描述语言将单独的作业根据依赖关系构成一个作业网络向系统进行投交和控制。
6 . design the complex job network . then according to the character of job network , we design the advance - scheduling algorithm based on barrier to schedule job network to shorten the waiting time 六、设计了旦有复杂依赖关系的作业网络,并根据作业网络特点,提出基于栅障的提汕凋度算法调度作业网络,减少了作业调度的等待时间。
It dissects the definition of job network , job network script , job network parameter and the impact of job network in a job manage system . it also introduces the method of design and implement the engine of jobmanage system , the schedule of jobs and execution of jobs 详细地介绍了作业网络的定义,作业网络脚本,作业网络参数以及作业网络在作业管理系统中的作用;作业管理系统引擎的设计及实现方法,作业网络的调度,作业网络的执行。
And based on this , i put my emphasis on the methods of graphic description of job and its implement , improved the mechanism of submitting job network automatically ( i . e . schedule driven submitting ) , thus , tasks that have to be performed regularly - such as collecting daily transaction data , creating daily reports , and generating monthly reports - can be automated and streamlined as much as possible so that enterprises can make better use of their valuable human resources ; i designed the mechanism of monitoring job network trackers of multiple computers , implemented the mechanism of controlling and synchronizing the job network trackers , this turns the centralized management of job network trackers in a distributed environment into realities 在此基础上,重点研究了mtzjms系统中作业的图形化描述方法及实现;强化了作业网络的自动提交(也称日程表驱动调度)机制,从而,尽可能的自动化并且更有效率的完成诸如收集每日的业务数据、创建日报、月报等周期性的任务,充分利用企业宝贵的人力资源;设计了多机器作业网络轨迹跟踪监视机制;实现了作业网络轨迹的控制和同步,从而实现分布式环境中对作业网络轨迹的集中管理。
Using of jdl in a jms has the following advantages : ( 1 ) define attributes of job network and unit jobs , and the complex reliant relation between unit jobs conventially , thus enable the jms to deal with complex operation logic . ( 2 ) define the job scheduling rule , thus enable the jms to deal with flexible , powful job scheduling function . ( 3 ) jdl is a platform independent language 在作业管理系统中引入jdl语言的优点有: ( 1 )方便地定义了作业网络和单元作业的属性以及单元作业间复杂的依赖关系,为作业管理系统提供了处理复杂业务逻辑的能力; ( 2 )定义了作业调度规则,为作业管理系统提供了灵活、强大的作业调度能力; ( 3 ) jdl语言具有平台无关的特性,基于jdl语言开发的作业管理系统可以容易地实现跨平台运行。
