Computing the Dark Universe

Abstract: 
Large-area sky surveys provide a wealth of cosmological information. Some of the results can be interpreted using analytical methods but, by and large, the use of N-body simulations -- individually, or in combination with analytical modeling -- has proven to be crucial in this effort. As statistical error bars from survey observations continue to shrink, simulations are entering a new regime in their use as analysis and prediction tools. Additionally, coming changes in supercomputer architectures provide another rationale for developing new simulation and analysis capabilities. In this talk I will describe the motivations behind the development of the HACC (Hardware/Hybrid Accelerated Cosmology Code) framework, its current status, including some recent results, and plans for the future.
