Abstract

The principal objective of this work is to develop portable and extensible programming tools for the development of object-oriented parallel finite element codes for structural engineering applications. An object-oriented parallel portability interface for message-passing operations has been designed and implemented. An existing object-oriented matrix library is currently being extended to support the management of distributed matrix data and parallel solution of linear systems of algebraic equations. By taking advantage of C++ object-oriented programming, both the class libraries provide clean and consistent user interfaces, which not only help to improve the clarity and expressiveness of the client parallel codes, but also hide implementation details and complexity from the user to ease parallel programming tasks. In this paper, the object-oriented design and implementation of the class libraries are discussed. The libraries were first developed and tested using a network of Sun SPARC 10 workstations. Application examples were then studied on two commercial parallel computers: the IBM SP1 and the Intel Paragon XP/S 10, for evaluation of the portability and efficiency of the present class libraries.

结构工程应用的面向对象并行编程工具

这项工作的主要目标是开发可移植和可扩展的编程工具，用于开发面向对象的并行有限元代码，用于结构工程应用。设计并实现了用于消息传递操作的面向对象并行可移植性接口。现有的面向对象矩阵库目前正在扩展，以支持分布式矩阵数据的管理和代数方程线性系统的并行解。通过利用c++面向对象编程，这两个类库都提供了干净一致的用户界面，这不仅有助于提高客户端并行代码的清晰度和表达性，而且还向用户隐藏了实现细节和复杂性，从而简化了并行编程任务。本文讨论了面向对象的类库的设计与实现。这些库首先是使用Sun SPARC 10工作站网络开发和测试的。然后在两台商用并行计算机:IBM SP1和Intel Paragon XP/S 10上研究了应用实例，以评估现有类库的可移植性和效率。
