摘　　要：支持科学和工程计算的ＢＬＡＳ（基本线性代数子程序）在高性能计算中有着重要作用．本文针对ＰｅｎｔｉｕｍＰｒｏ的体系结构特点，提出了一些优化方法使得ＢＬＡＳ在ＰｅｎｔｉｕｍＰｒｏ上计算性能达到最佳．测试表明，在２００ＭＨｚ的ＰｅｎｔｉｕｍＰｒｏ上ＢＬＡＳ３的速度可达１１２Ｍｆｌｏｐｓ．BLAS is basic linear algebra libraries for science and engineering applications.It plays an important role in high performance computing. By identifying and optimizing frequently used, numerically intensive operations, BLAS can help in reducing the cost of computation, enhancing portability, and improving productivity.By taking advantage of the architectural features of Pentium Pro, a series of optimized methods are proposed to implement BLAS on Pentium Pro so that BLAS can perform optimally on Pentium Pro systems. The testing results demonstrate that the speed of BLAS3 can reach 112Mflops on 200MHz Pentium Pro.
