Comparative Analysis of Multicore and Grid Based Execution of SWAT Model

Abstract

The paper presents a comparative analysis between the Multicore and the Grid execution of SWAT hydrological model. We try to emphasize the advantages brought by the Grid infrastructure, especially for large scale applications which require large number of executions and huge data resources. We use as a case study a large scale hydrological model, built using the Arc SWAT program, which covers the Danube River Basin and we draw the conclusions derived from these experiments, pointing out the benefits brought by the Grid architecture.
