摘要
MM5模式系统常被用在气象科研和天气预报当中,通常运行在商业版本的Unix/Linux系统上,对非商业版本的类Unix系统并不太友好。文章详细介绍了MM5V3.7在高性能免费Unix操作系统FreeBSD 6.0上的移植及其应注意的问题,并通过一个个例分别在FreeBSD 6.0和Red Hat Advanced Server 4(RHAS 4)上的运行来比较其效率。通过对比发现,FreeBSD的性能要比通常所用的Linux系统有较大的提高,这对于改善实际业务中的时间迫切性问题有很大的意义。
The MM5 model system is used widely in meteorological research and weather prediction operation, but for some unknown reasons, it runs usually on the commercial version of Unix and Linux systems and is unamiable to free Unix-like systems. The transplantation of MMSV3 on the high-performance operating system FreeBSD is introduced in detail. FreeBSD is a free Unix system with particularly high performance. The run time on FreeBSD 6.0 is compared with that on RHAS 4 （Red Hat Advanced Server 4）, and it is found that FreeBSD＇s performance is higher obviously than RHAS＇. It is of great significance to operational forecasting.
