Lumina: largest early-universe simulation runs on 15,000 GPUs

A team at the Center for Astrophysics | Harvard & Smithsonian built Lumina, the largest cosmological radiation-hydrodynamics simulation of the early universe. It models how ordinary matter, dark matter and radiation interacted during the first 2 billion years after the Big Bang and required more than 15,000 GPUs.

• Simulation covers the first 2 billion years of the universe
• The project used more than 15,000 GPUs
• Lumina tracks hydrogen and helium turning into their modern form
• Results will be compared with JWST and Roman telescope data
