Three-Dimensional (3D) Large Fluid Flow Computations for U.S. Army Applications on KSR-1, CM-200, CM-5, and Cray C-90.
Abstract
The thrust of this research is to investigate the use of emerging massively parallel computer architectures for production type fluid flow applications. Typical flow computations in a ballistic simulation have reached a stage where a grid set involving a couple of million points are needed for adequate understanding of the flow behavior and computing the resulting forces acting on a projectile with a complex geometrical shape. For acceptable turnaround time, the simulation requires a system with large memory and high performance. Because of the hardware scalability and availability of large In-core memory, the emerging massively parallel processors (MPP) architectures such as Connection Machine's CM.5 and Kendall Square Research KSR-1 have become attractive for ballistic computations. Thus, this research is focused on implementation of complex real-world applications (not simple scaled down problems) on MPPs with the goal of sustainable performance. Because performance measurements obtained using the kernel of the full application and/or scaled down application size or 2-D cases could lead to considerably higher performance estimates, these factors are discussed in light of results from full 3.D applications obtained on MPPs.
