Abstract:
In this paper, we present the application of element free Galerkin (EFG) method to analyze two-dimensional elastostatics problems, for example, cantilever beam. MPI parallel programming process is exploited to increase the computational efficiency and to mitigate the time consumed in the tremendous calculations using the element-free Galerkin method. We propose a powerful computation efficient architecture for CPU Cluster Using DRBL. The architecture help administrator to quickly deploy and manage CPU Cluster environment [15], it also bring benefit of computational efficiency in scientific computing. We have executed job on DBRL Cluster. The total time, speedup and efficiency have estimated for cantilever beam problem. We execute parallel implementation on DRBL Cluster [10]. For 16 cores, the speedup and efficiency are obtained to be 12.34 and 77.125% in cantilever beam problem.
