摘要

STEM-II是一个欧拉空气质量模型，它在一个综合框架中模拟运输、化学转化、排放和沉积过程。由于控制方程是非线性的、高耦合的和刚性的，该模型的计算量很大。这项工作的目的是通过代码的并行实现来减少每次模拟所需的CPU时间，以获得实时预测。展示了使用MPI库在分布式内存系统上实现的改进。

The STEM-II air quality model on a distributed memory system

STEM-II is an Eulerian air quality model which simulates transport, chemical transformations, emissions and depositions processes in an integrated framework. The model is computationally intensive because the governing equations are non-linear, highly coupled and stiff. The purpose of this work is the reduction of CPU time needed by each simulation by means of the parallel implementation of the code to obtain real-time predictions. The improvements achieved on distributed memory systems using the MPI library are shown.
