Efficient numerical algorithms play an increasingly important role in computational sciences to make large scale computer simulations tractable. Solution of very large sparse matrices has been one of the most time-consuming parts of many large scale high performance computer simulation problems. One of the important tasks in high performance scientific computing is to identify which solver is suitable for what class of applications (sparse matrices), and which sparse matrix can be solved by what solver. We will use the techniquesand ideas in knowledge discovery and data mining to extract useful information and special features from unstructured sparse matrices and to design appropriate strategies to match sparse matrices and solvers.The outcome of this exploratory study is some important preliminary data and database to demonstrate the feasibility of building a software environment for high performance scientific computing applications based on mining sparse matrices and extracting features.

有效的数值算法在计算科学中起着越来越重要的作用，可以使大规模的计算机模拟可进行。稀疏矩阵的解决方案一直是许多大型高性能计算机模拟问题中最耗时的部分之一。高性能科学计算中的重要任务之一是确定哪种求解器适用于哪些类别的应用程序（稀疏矩阵），哪些稀疏矩阵可以通过求解器来解决。我们将在知识发现和数据挖掘中使用技术和思想来提取有用的信息和特殊功能，并设计出适当的策略，以匹配稀疏矩阵和求解器。这项探索性研究的结果是一些重要的初步数据和数据库，以证明基于高度计算的高性能应用程序的软件环境，并提取基于Sparse Matrices sparse Matrices的可靠性。
