Implementación del modelo hidrológico Catamayo-Chira sobre un entorno de computación distribuida

Abstract

The development of this implementation project arises from an unavoidable reality at the present time, as it is the lack of computational power of a computer sequence (Von Neumann principle) to execute a problem that demands high levels of processing and immediate response times. Faced with this problem, the Catamayo Chira hydrological model is framed, which needs to execute a large number of simulations of the SWAT module. It is proposed to execute the model using parallel or distributed platforms that allow to solve the requirements of the problem exposed by this This raises the issue as follows: "Implementation of the Catarnayo-Chira Hydrological Model on a distributed computing environment", whose general objective for its implementation is: 'To execute a large number of simulations of the hydrological model obtaining immediate response times. "For the execution of the hydrological model it was chosen to implement on a parallel cluster which brings together hardware and software components destined for this purpose with total integration, obtaining parallelism at the process level granted by the Lam-mpi message exchange protocol and parallelism Level of data provided by the programming language R, in turn these make use of libraries and tools that must be configured to mating with the middeware OSCAR in charge of providing high performance. In addition, a modification to the SWAT module in its main block should have been made to adjust it to the data inputs of the basin previously designed by the hydrologists; With this adjusted to the needs of the calculation, an integrating program was constructed in R for the execution of the simulation using a method of correction of flow and events produced on the Catamayo-Chira basin.
