Abstract :
In this scenario, computational fluid dynamics simulations of turbulence are performed with 64 GPUs and an optimized CFD algorithm using communication/computation overlapping. Detailed timings reveal that the GPUs´ internal calculations are so efficient that operations related to data exchange between compute nodes now cause a scaling bottleneck on all but the largest problems.
