Cosmological simulations present well-known difficulties scaling to large core counts because of the large spatial inhomogeneities and vast range of length scales induced by gravitational instability. These difficulties are compounded when baryonic physics is included which introduce their own multiscale challenges. In this talk I review efforts to scale the Enzo adaptive mesh refinement hydrodynamic cosmology code to O(100,000) cores, and I also discuss Cello--an extremely scalable AMR infrastructure under development at UCSD for the next generation of computer architectures which will underpin petascale Enzo.

Blue Waters: A Super-System to Explore the Expanse and Depth of 21st Century Science
While many people think that Blue Waters means a single Power7 IH supercomputer, in reality, the Blue Waters Project is deploying an entire system architecture that includes an eco-system surrounding the Power7 IH system to make it highly effective, ultra-scale science and engineering. This is what we term the Blue Waters "Super System" which we will describe in detail in this talk along with its corresponding service architecture.
