摘要

作为难以并行化的计算问题的一个实例，我们讨论了对二维薛定谔方程进行积分的量子反应散射应用的并行化问题。通过对计算过程的详细分析，找出了在MIMD-DM机器上运行应用程序时导致性能下降的低效率来源，并相应地构建了并行模型。通过一些试验计算，验证了所采用模型的适用性。

On the optimization of a task-farm model for the parallel integration of a two-dimensional Schrodinger equation

As a case study of computational problems difficult to parallelize we discuss the parallelization of a quantum reactive scattering application integrating a two dimensional Schrodinger equation. From a detailed analysis of the computational procedure, sources for inefficiency causing a performance degradation when running the application on a MIMD-DM machine were singled out and the parallel model was structured accordingly. The suitability of the model adopted was checked by running some test calculations.
