The Weather Research and Forecasting (WRF) model does not usually show an adequate scalability for small‐sized domains in large computing platforms. With this in mind, we propose a novel asynchronous software architecture for the WRF model that decouples the calculation of the solar radiation from the rest of the model. The experimental evaluation was conducted on real‐world data for forecasting the...
In this paper we address the use of high performance computing techniques with the aim of accelerating the runtime of a numerical model for the South Atlantic Ocean. This numerical model is a component of a larger system, that includes higher precision models to compute the hidrodynamics of the Río de la Plata river. Our work includes, in a first stage, a thorough study of the use of traditional HPC...
Generalized Lyapunov equations play an important role in bilinear model order reduction and linear stochastic differential equations. They also arise solving generalized Riccati equations from stochastic control. In this paper we present a high-performance implementation of a Generalized Lyapunov equation solver based on the matrix sign function method for heterogeneous platforms, composed by a multi-core...
