Simulating Galaxies With Supercomputers

An anonymous reader writes "Over in the UK Durham University is tasking its supercomputing cluster with nothing less than recreating how galaxies are born and evolve over the course of billions of years. Even with 800 AMD processor cores at its disposal the university is still hitting the limits of what is possible."

    800 cores.... that's like 134 CPU's, With 4 CPU's per node, it's only 34 Nodes. A rack holds 48u.

    So they have a problem that takes more then one rack of modern computers to handle?

    This is nothing. For my kindergarten thesis, I used galaxies to simulate supercomputers.

    Or two GPUs.

    If it can run Crysis it can simulate galaxies.

    Has anyone else been bothered the fact that energy is quantized?

    Even more significant is that there's an intrinsic speed limitation in a simulation.

    When you simulate a continuous medium by dividing it into small space and time steps, there's a speed "c" that's equal to the space step divided by the time step which cannot be exceeded by anything in the simulation.
