摘要
本文通过对Hypre软件包的数据接口进行研究,提出了一种新数据接口:文件接口。该接口避免在某一个进程生成一个与总刚度矩阵同规模的大矩阵,节省了计算机内存开销和计算时间,方便了用户调用Hypre系统的解法器。对进行大规模问题的计算具有重要的意义。
This paper discusses data interface of Hypre software and proposes a new algorithm for data interface ： file-interface.The interface avoids getting a matrix as large as global stiff matrix on certain process.It reuduces the cost for memory of the computer and cpu time.It is also useful for users calling the solvers of Hypre.The algorithm shows that it is very important to solve linear systems arising from problems posed on extremely large,unstructured grids.
