摘要

讨论了动态精度在不动点迭代数值算法中的应用。这些算法广泛应用于数值密集型的科学应用中。穆勒方法就是这样一种算法，它可以检测任意函数的复根。该算法在包括MasPar MP-1大规模并行处理器和Cray Y-MP矢量处理器在内的各种体系结构上的DP中实现。结果表明，在多范围架构下，使用DP可以显著提高迭代算法的速度。

Dynamic precision iterative algorithms

The authors address the use of DP (dynamic precision) in fixed point iterative numerical algorithms. These algorithms are used in a wide range of numerically intensive scientific applications. One such algorithm, Muller's method, detects complex roots of an arbitrary function. This algorithm was implemented in DP on various architectures, including a MasPar MP-1 massively parallel processor and a Cray Y-MP vector processor. The results show that the use of DP can lead to a significant speedup of iterative algorithms on multiple-range architectures.<>
