Abstract

Large-volume sky surveys have accessed the Universe´s vast temporal and spatial expanse via a remarkable set of measurements, and many more are sure to follow. To make new predictions for these cosmological observations and to properly interpret them, large-scale numerical simulation and modeling has become an essential tool. Here, the authors discuss Hardware/Hybrid Accelerated Cosmology Code (HACC), an extreme-scale N-body cosmology code and its associated analysis framework, focusing on the complexity of the analysis workflow, which is as important as running the underlying simulation.
