Exploring the Millennium Run - Scalable Rendering of Large
One of the most popular simulations is the Millennium Run, where more than 10 billion particles have been used to trace the evolution of the matter distribution in a cubic region of the Universe with over 2 billion light-years on a side, resulting in terabytes of stored output The simulation itself ran 28 machine days at 0 2 Tflops using 1 Tbyte RAM By comparing the simulation results to large
