Description

Because of their leading research in numerical simulation using parallel computing practices, Fraunhofer SCAI and the Institute for Numerical Simulation (INS) at the University of Bonn have officially become one of the first German NVIDIA CUDA Research Centers. The research on parallelization of existing simulation codes to run on machines with multiple graphics processing units (GPUs) is led by Prof. Dr. Michael Griebel.

In particular at the INS the goal is to develop a massively parallel, completely multi-GPU based high performance two-phase fluid solver. To this end, the INS software NaSt3DGPF is adapted. Preliminary results show a speedup by an order of magnitude for the whole fluid solver on one GPU and a good scaling for multi-GPU.
