Parallel computing for implicit scheme of numerical simulation for laser propulsion

Parallel computing has been applied in many fields, and the parallel computing platform system, PC cluster based on MPI (Message Passing Interface) library under Linux operating system is a cost-effectiveness approach to parallel compute. In this paper, the key algorithm of parallel program of explosion and impact is presented. The techniques of solving data dependence and realizing communication between subdomain are proposed. From the test of program, the portability of MMIC-3D parallel program is satisfied, and compared with the single computer, PC cluster can improve the calculation speed and enlarge the scale greatly.

Establishing a methodology of parallel computing which considers collaborative computation with other computer codes and/or softwares which may be installed in different computers is important for collaborative parallel computing with other softowares of multibody system which are developed under separate developing environments. In this paper, a fundamental parallel computing procedure is proposed by means of DAE approach in multibody dynamics. Then constraint errors in DAE are analyzed and a stabilization procedure of constrained errors is derived to be introduced into the proposed parallel computing procedure. By modifying standard DAE of multibody system, each subsystem is obtained by decomposing a total system into several subsystems so that parallel computation can be proceeded. The proposed method is effective for combining multibody subsystems which are developed in different developing environments. This paper describes a proposed procedure, and presents numerical simulation of a fundamental example to show the effectiveness of the proposed method.
