摘要 A web service wrapping approach for command line programs,which are commonly used in scientific computing,is proposed.First,software architecture for a basic web service wrapper implementation is given and the functions of the main components are explained.Then after a comprehensive analysis of data transmission and a job life cycle model,a novel proactive file transmission and job management mechanism is devised to enhance the software architecture,and the command line programs are wrapped into web services in such a way that they can efficiently transmit files,supply instant status feedback and automatically manage the jobs.Experiments show that the proposed approach achieves higher performance with less memory usage compared to the related work, and the usability is also improved.This work has already been put into use in a production system of scientific computing and the data processing efficiency of the system is greatly improved. 提出了一种科学计算领域中常用的命令行程序web服务包装方法.首先给出了实现一个基本的web服务包装器的软件架构,并对主要组件的功能进行了解释.进而经过对数据传输和作业生命周期的深入分析,设计了一种新颖的文件传输和作业管理机制用以增强该软件架构,使得在命令行程序被包装成web服务的同时,保证了文件的高效传输,运行状态的即时反馈和作业的自动管理.对比实验表明,该方法在使用了较少内存的前提下提高了程序运行性能,定性比较显示程序的易用性也有所提高.本工作已经在实际的科学计算系统中得到了应用,极大地提高了系统的数据处理效率.
