Abstract:In order to run a numerical models, the Linux-OS installation, the compiling and parallel environment setup process, and other correlative software are emphatically introduced with less about their principles. All the software can be got from the internet, so it is very suitable for basic meteorological stations to set up their parallel computer systems to solve the contradiction between computer sources and development of practical operation. The systems are the bases to do the finer forecasting, and can also be applied to sciences research.
