  • KOPPA (Kinetic Octree Parallel PolyAtomic) is a parallel numerical code for the simulation of rarefied gas dynamics. It is based on a library named PABLO (PArallel Balanced Linear Octree) used to manage octree grids in parallel. The main issue with such numerical codes is the very high execution time which can become prohibitive for some industrial applications. Thanks to the SHAPE project, important improvements have been achieved with respect to execution time and scalability. In particular, some parts of the code have been reimplemented to suit better a MIC (Multi Integrated Cores) architecture. So far, the computational time requirements have been decreased by a factor of almost 8 and a good scalability has been obtained up to 64 processors against 16 initially.
