Numerous recent federal and academic reports comment on the inadequacy of software support for High Performance Computing. Among other deficiencies, much of the software designed for HPC, such as numerical libraries that encapsulate complicated and widely used algorithms, is considered too hard to use, too inefficient (too low a fraction of peak and/or not scalable), or both. However, the linear algebra libraries LAPACK and ScaLAPACK are frequently mentioned as positive examples whose success in this area should be emulated.This work involves the maintenance, enhancement, hardening, and modernizing of the LAPACK and ScaLAPACK libraries in the context of the ongoing revolution in processor architecture and system design. These libraries are widely used: there were over 160 million web hits (excluding bots) from 2004-2009, and they have been adopted by many vendors as the basis of their own libraries: Intel, Cray, IBM, HP, Fujitsu, NEC, NAG, IMSL, and the Mathworks (producers of Matlab). There is every reason to believe, therefore, that improving these stalwart components of the HPC software stack will have a very large impact.

许多最近的联邦和学术报告评论的软件支持高性能计算的不足。在其他缺陷中，许多为HPC设计的软件，例如封装复杂和广泛使用的算法的数值库，被认为太难使用，太低效（峰值的分数太低和/或不可扩展），或两者兼而有之。然而，线性代数库LAPACK和ScaLAPACK经常被提到作为积极的例子，其成功在这一领域应仿效。这项工作涉及的维护，增强，加固，和现代化的LAPACK和ScaLAPACK库在处理器体系结构和系统设计的持续革命的背景下。这些库被广泛使用：从2004年到2009年，有超过1.6亿的网络点击量（不包括机器人），它们被许多供应商采用作为自己库的基础：英特尔，Cray，IBM，HP，富士通，NEC，NAG，IMSL和Mathworks（Matlab的生产商）。 因此，我们有充分的理由相信，改进HPC软件栈的这些坚固组件将产生非常大的影响。
