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 1.6k IBM BG/L nodes and the evolutionary optimization of long wavelength stabilities in aircraft wakes.
