摘要: 作业管理一直是网格技术中的热点问题,其中对于作业的描述是作业管理中的首要任务。本文针对作业描述展开分析,设计基于任务通信的作业描述语言CJDL(Communication Job Description Language)。CJDL以XML语言为基础,具有可扩展性,其优势在于可以描述各任务之间的通信关系以及对资源的需求,从而可以进一步完成作业的自动并行化和资源的匹配,为作业的分派、运行等过程奠定基础。

Abstract: Job management has been a hot issue in grid technology. The job description is the first task in the job management. This paper analyzes the job description, designs the job description language(CJDL) based on task communication. CJDL based on the XML language, with scalability, its advantages is that it can describe the communication between tasks and demands on resources. It can accomplish the automatic parallelization of job and resource matching further, and lay a foundation for job spawn and running and so on.

Key words: job description language, grid, parallelization, XML, task communication
