Foil 4 Summary of Sec 3: NAS Parallel Benchmarks:The CFD Kernels

From Introduction to Physics and Numerics of NAS Benchmarks CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox


A Collection of Iterative PDE Solvers embedded in a Pseudo CFD application program is proposed (and now used by community) for the performance evaluation of CFD Codes on highly parallel processors. The solvers are also now used as a general benchmark for different parallel machines. The pseudo application program is stripped of complexities associated with real CFD application programs, thereby enabling a simpler description of the algorithms. However it is capable of reproducing the essential computation and data access/movement characteristics of large scale state of the art CFD codes. These latter features make the CFD kernels suitable for CPS713 as a framework for discussing essential computer science issues in CFD.
