Benchmarks and profiling of the WRF model within the Hydro-Meteorological Observatory of the Province of Córdoba

摘要

The Government of the Province of Córdoba, together with the National Meteorological Service (SMN), the National Commission of Space Activities (CONAE), the National University of Córdoba (UNC), the National Institute of Agricultural Technology (INTA) and the INVAP, formed the Hydro-Meteorological Observatory (HMO) of the Province of Córdoba [1]. The generation of short-term forecasts with high spatial resolution is one of the objectives of the HMO, given that they are a fundamental tool for the prediction of severe hydro-meteorological events that produce negative socioeconomic impacts in the region. The HMO uses the Weather Research and Forecast (WRF) model for research and operationally. That is why the need to find the optimal hardware and software requirements for model execution was raised. With this objective, in this work we analyzed the execution performance of the WRF model in different computer scenarios. Although this work is presented within the framework of the HMO of the Province of Córdoba, what is analyzed contemplates the different realities of different institutions with the same initiative. Then the results are presented, taking into account the user's computation needs, in order to define an optimal system in the computing / cost relation.
