面向生物信息学计算的网格工作流系统

针对生物信息学网格计算需求,提出了一种网格工作流管理系统模型,系统以Web方式为用户提供服务,通过与软件模块的交互实现良好的可定制的人机交互界面,使得不熟悉网格计算和工作流系统的人也可以快捷直观地操作使用.该系统能够自动地对工作流任务进行调度,然后通过网格中间件进行执行,并对任务进行监控和管理.论述了该系统的框架和实现原理,通过一个生物信息学计算实例说明工作流的定义、描述和使用流程;并且,通过与中国教育科研网格公共支撑平台CGSP工作流系统的对比,说明了该系统在可视化、便捷性上更符合生物信息学计算需求的特点.

A grid workflow system for bioinformatis computing

A workflow management system of bioinformatics grid computing was proposed,which utilizes the web method to serve users and realizes an editable interface via interaction with software module,so that one can do workflow projects conveniently without knowing much about grid computing and workflow system.This system can also automatically schedule projects and execute them via grid middleware.It can monitor and manage projects as well.The framework and the module of the system was introduced,then the workflow definition,description and usage by a bioinformatics computing example was explained.The system was compared to the CGSP workflow system and showed that this system is more favorable for bioinformatics users both in visualization and convenience.
