Message-Passing Program Development by Ensemble
We present Ensemble, a message-passing implementation methodology, applied to PVM. Ensemble overcomes problems and complexities in developing applications in messagepassing environments (MPE). Applications are specified by scripts, which represent Process Communication Graphs (PCG) annotated with information specific for an MPE, and by reusable executable components. A loader program interprets...
متن کاملDomain Decomposition Methods for Parallel Solution of Shape Sensitivity Analysis Problems
This paper presents the implementation of advanced domain decomposition techniques for parallel solution of large-scale shape sensitivity analysis problems. The methods presented in this study are based on the FETI method proposed by Farhat and Roux1 which is a dual domain decomposition implementation. Two variants of the basic FETI method have been implemented in this study: (i) FETI-1 where t...
متن کاملMPI-based parallel finite element approaches for implicit nonlinear dynamic analysis employing sparse PCG solvers
This paper presents three formulations combining domain decomposition based finite element method with linear preconditioned conjugate gradient (LPCG) technique for solving large-scale problems in structural mechanics on parallel processing machines. In the first formulation called the Global Interface Formulation (GIF), the PCG algorithm is applied on the assembled interface stiffness coeffici...
متن کاملParallel Domain Decomposition for 1-D Active Thermal Control Problem with PVM
this paper describes a 1-D Active Thermal Control Problem (1-D ATCP) with the use of Stationary Iterative Techniques (Jacobi and Gauss-Seidel) on the discretization of the resulted matrices. Parallelization of the problem is carried out using Domain Decomposition (DD) parallel communication approach with Parallel Virtual Machine (PVM) to enable better flexibility in parallel execution, and grea...
متن کاملSolution of Nonlinear Hardening and Softening type Oscillators by Adomian’s Decomposition Method
A type of nonlinearity in vibrational engineering systems emerges when the restoring force is a nonlinear function of displacement. The derivative of this function is known as stiffness. If the stiffness increases by increasing the value of displacement from the equilibrium position, then the system is known as hardening type oscillator and if the stiffness decreases by increasing the value of ...
