Performance engineering for the lattice Boltzmann method on GPGPUs: Architectural requirements and performance results

GPUs offer several times the floating point performance and memory bandwidth of current standard two socket CPU compute nodes, e.g. NVIDIA C2070 vs. Intel Xeon Westmere X5650. The lattice Boltzmann method (LBM) has been established as a flow solver in recent years and was one of the first flow solve...
