本文介绍了HPC中的基准测试工具和数值计算库，包括LINPACK、BLAS、ATLAS、LAPACK、MKL和NPB。LINPACK用于解决线性方程组，已被LAPACK取代。BLAS提供基本线性代数操作，ATLAS是自动调优的线性代数软件。LAPACK包含高效的线性系统求解和特征值问题算法，依赖于BLAS。Intel MKL是针对Intel处理器优化的数学库。NPB则是一套用于评估并行超级计算机性能的基准测试程序。

LINPACK

LINPACK is a collection of Fortran subroutines that analyze and solve linear equations and linear least-squares problems. The package solves linear systems whose matrices are general, banded, symmetric indefinite, symmetric positive definite, triangular, and tridiagonal square. In addition, the package computes the QR and singular value decompositions of rectangular matrices and applies them to least-squares problems. LINPACK uses column-oriented algorithms to increase efficiency by preserving locality of reference.
LINPACK was designed for supercomputers in use in the 1970s and early 1980s. LINPACK has been largely superceded by LAPACK, which has been designed to run effici
