A Portable LAPACK Library for Network Distributed Computing

数学库是支持应用软件开发的编程环境的重要组成部分。虽然数学库在顺序计算机上广泛使用，但对于并行计算机来说却很少见--特别是在跨工作站网络进行分布式计算的情况下。该项目将进行研究，为网络分布式计算机提供LAPACK库的可移植版本。之所以选择LAPACK，是因为它可能是当今使用的最重要的数学库。这个项目要解决的关键研究问题是找到支持在工作站网络上发现的粗粒度的高效执行的数据分解和算法。这些结果将作为可行性研究的一部分进行分析。它们将构成执行图书馆第二阶段提案的工作计划的基础。

Math libraries are an important part of programming environments that support the development of application software. While broadly available on sequential computers, math libraries are rare for parallel computers - especially in the case of distributed computing across networks of workstations. This project is to conduct research leading to a portable version of the LAPACK library for network distributed computers. LAPACK was selected since it is probably the most important math library in use today. The key research issues to resolve in this project are to find data decompositions and algorithms that support efficient execution with the coarse granularities found on networks of workstations. These results will be analyzed as part of the feasibility study. They will form the basis of the work plan for implementing the library for the Phase II proposal that would follow.
