Aiming at the high performance computing(HPC) needs of computational fluid dynamics(CFD)
a cluster system consisting of 36 Itanium 2 processors and Infiniband network was constructed.The linpack value achieved 188.6 GFlops after optimization.The cluster was extended to a parallel CFD numerical simulation platform. A three-dimension flow field model of a tactical missile was built.The performance and precision of the parallel platform were measured.Results show that the hardware and software configuration of the parallel platform is appropriate
and that it can meet the needs of medium and large sized CFD applications.
