Performance Researches of Navier-Stokes Equation’s Parallel Implementation
LU Xinda · 2004
Navier-Stokes equations have been widely applied in CFD (computational fluid dynamics) field. This paper describes two methods of its numerical simulating in emulated CFD:Block Tri-diagonal and Scalar Pentagon-diagonal. After analyzed the data dependencies in solving process, it gives different strategies of parallel implementation, which is uni-partition and multi-partition of domain decomposition methods(DDM), and discribes its corresponding performance studies of the computations, the communications and memory requirements. At last, it gives some test results.
