Abstract: This work focuses on the application of parallel processing to element-free Galerkin method analyses, particularly in the formulation of the stiffness matrix, the assembly of the system of discrete equations, and the solution for nodal unknowns. The objective is to significantly reduce the analysis time while retaining high efficiency and accuracy. Several relatively low-cost Intel Pentium-based personal computers are joined together to form a parallel computer. The processors communicate via a local high-speed network using the Message Passing Interface. Load balancing is achieved through the use of a dynamic queue server that assigns tasks to available processors. Benchmark problems in 3D structural mechanics are analyzed to demonstrate that the parallelized computer program can provide substantially shorter run time than its serial counterpart, without loss of solution accuracy.
