Abstract: We present Vortex Methods implemented in massively parallel computer architectures for the Direct Numerical Simulations of high Reynolds numbers flows. Periodic and non-periodic domains are considered leading to unprecedented simulations using billions of particles. We discuss the implementation performance of the method up to 16k IBM BG/L nodes and the evolutionary optimization of long wavelength instabilities in aircraft wakes.
