A Software Package for Solving Large, Sparse Linear Systems of Equations in a Vector Processing Environment

在过去的十年中，大规模科学计算“技术”的两个潜在的最重要的进步是稀疏矩阵（迭代）算法和向量处理。该计划是建立一个软件包，将这两种进步的力量带到科学界，而不必迫使科学界成为其中任何一种技术的专家。该软件包是V-PCGPAK，一个通用矢量、稀疏矩阵求解器。V-PCGPAK将基于PCGPAK，即用于大型，稀疏，非对称线性方程组迭代解的预条件共轭梯度子程序包。此类系统的解决方案通常是大型工程和科学计算机程序的计算密集型内核。

Over the past decade, two of the potentially most important advances in the "technology" of large scale scientific computing are sparse matrix (iterative) algorithms and vector processing. The plan is to build a software package that will bring the power of both advances to the aid of the scientific community without forcing that community to become expert in either technology. The software package is V-PCGPAK, a general vector, sparse matrix solver. V-PCGPAK will be based on PCGPAK, the Preconditioned Conjugate Gradient Package of subroutines for the iterative solution of large, sparse, nonsymmetric systems of linear equations. The solution of such systems is usually the compute- intensive kernel of large engineering and scientific computer programs.
