基于Babel的构件程序设计

为了解决高性能科学计算程序设计当中存在的开发难度大，开发周期长以及时开发人员要求高等问题，人们已经开始将软件构件技术引入该领域。由美国能源部、犹他州大学、印弟安那大学等联合提出的CCA便是研究高性能科学计算构件技术的项目之一。本文主要介绍了CCA以及CCA框架下的语言互操作工具－Babel的相关情况，并且通过NPB基准测试程序IS详细描述了Babel的使用，分析了基于Babel的程序设计对程序性能的影响。初步实验表明Babel能够有效解决语言的互操作问题，在面向科学计算的构件程序设计环境中能够发挥关键作用。

Component-based Programming Using Babel

In recent years, component technology has been imported to high-performance scientific computing field in order to solve problems of complexity, reuse, and interoperability for high-performance scientific computing software. The CCA, brought forward by various national laboratories U.S. Department of Energy and collaborating academic institutions, is a project to develop a common framework that will allow scientists to reuse computer codes on today's high-performance computing systems, and to allow interoperability between those codes. This paper primarily introduces CCA and Babel, a language interoperability tool in CCA framework. We also demonstrate the component-based programming using Babel; analyze the performance costs associated with Babel. Our preliminary experiment indicates that Babel do well in language interoperability and it suits the high-performance scientific computing.
