| Abstract: | This paper describes that the model and postprocessing calculations are executed parallelly at JOB level on the computer M360-AP with two additional processors in the T42 assimilation forecasting quasi-operational system in the National Meteorological Center (Beijing). The results show that the multitasking parallel computing technique makes 5-day NWP completed at least 60 minutes ahead of time and its speed-up factor is equal to 1.23 |
