Abstract

We present a case study of the alternatives and design trade-offs encountered when adapting an established numerical library into a form compatible with modern component-software implementation practices. Our study will help scientific software users, authors, and maintainers develop their own roadmaps for shifting to component-oriented software. The primary library studied, LSODE, and the issues involved in the adaptation are typical of many commonly used numerical libraries. We examine the adaptation of a related library, CVODE, and compare the impact on applications of the two different designs. The LSODE-derived components solve models composed with CCA components developed independently at the Argonne and Oak Ridge National Laboratories. The resulting applications run in the Ccaffeine framework implementation of the common component architecture specification. We provide CCA-style interface specifications appropriate to linear equations, ordinary differential equations (ODE), and differential algebraic equations (DAE) solvers.

我们提出了一个案例研究，在将已建立的数值库调整为与现代组件软件实现实践兼容的形式时遇到的替代方案和设计权衡。我们的研究将帮助科学软件用户、作者和维护人员开发他们自己的路线图，以转向面向组件的软件。所研究的主要库LSODE及其适应所涉及的问题是许多常用数字库的典型问题。我们研究了相关库CVODE的适应性，并比较了两种不同设计对应用程序的影响。lsode衍生组件解决了由阿贡和橡树岭国家实验室独立开发的CCA组件组成的模型。生成的应用程序在通用组件体系结构规范的咖啡因框架实现中运行。我们提供适合线性方程、常微分方程(ODE)和微分代数方程(DAE)求解器的cca风格接口规范。
