摘要

一个求解核，LSOLVE，已添加到ANSYS，一个有限元分析代码。LSOLVE是一个rank-n更新例程，可以在具有分层内存结构的并行机和向量机上有效地实现。通过检查Alliant并行计算机上使用的Fortran代码，描述了LSOLVE在并行计算机上的实现。LSOLVE在标准ANSYS基准测试中的性能证明了它的实用性。

Tuning the ANSYS kernel LSOLVE for a parallel computer

A solver kernel, LSOLVE, has been added to ANSYS, a finite-element analysis code. LSOLVE is a rank-n update routine that can be implemented efficiently on parallel and vector machines with a hierarchical memory structure. An implementation of LSOLVE on a parallel computer is described by examining the Fortran code used on the Alliant parallel computer. The utility of LSOLVE is demonstrated by performance on standard ANSYS benchmarks.<>
