| Abstract | Monitoring agriculture activities has benefited so much over last 20 years from the advances in Remote Sensing (RS). A crop growth model holds a vital role in agricultural monitoring system. To run crop models are quite useful especially for prediction. however, the parameter determination in large area is in practical a difficult task. A method was proposed by Ines. (2002) to optimize the input parameters of a one-dimensional crop model (SWAP) by assimilating simulated evapotranspiration with remote sensing data. The optimization is based on GA (Genetic Algorithm). Howye\er. it requires huge computational time, which is one of the constraints in practical implementation of the method. Cluster is a type of parallel and distributed processing system, provides us N\ith increased computing capabilities and which can help to remove the computational time constraints. Thus, a parallel crop model (SWAP-GA) procedure for remote sensed images is considered. In this study, a numerical experiment with three different SWAP-GA cluster implementation schemes is presented to show the strengths and limitations of these proposed approaches using Optima, Magi and Maeka clusters. By using these three clusterimplementing methods. the computational time constraints of SWAP-GA are decreased. Additionally, different Genetic Equations are found for calculating the estimate time to run SWAP-GA in cluster computers with known parameters |
