Cosmology is in a scientifically very exciting phase. Two decades of surveying the sky have culminated in the celebrated “Cosmological Standard Model." Yet, two of its key pillars, dark matter and dark energy -- together accounting for 95% of the mass-energy of the Universe -- remain mysterious. Deep fundamental questions demand answers; to address these burning questions, survey capabilities are being exponentially improved. The new observations will pose tremendous challenges on many fronts -- from the sheer size of the data that will be collected to its modeling and interpretation. The interpretation of the data requires sophisticated simulations on the world's largest supercomputers.

In this talk I will introduce HACC, the Hardware/Hybrid Accelerated Cosmology Code, which is being developed to combat the tremendous computational challenge to simulate our Universe. I will discuss some results from our recent work on confronting the simulated with the real Universe.
