Abstract :
Simulations run on the largest available parallel supercomputers are answering the question of how today´s rich cosmic structure developed from a smooth, near featureless early universe. The paper presents two such simulations which illustrate how algorithm and implementation strategies can be optimized for specific cosmological problems. The first aims to outline structure in the largest possible volume of the universe. The second treats a single galaxy cluster´s evolution with the highest possible resolution
