How did the  universe began from a hot, dense uniform phase and evolved into what we  observed today with plentiful structures composed of stars, galaxies,  clusters of galaxies, super-clusters, voids and filaments? It is the  main question in modern cosmology. Recently, an extremely large  numerical experiment has been made on Lenovo DeepComp 7000 supercomputer  installed in Computer Network Information Center of CAS.  The  experiment is part of the “Pangu Project” led by the Computational  Cosmology Consortium of China (C4) – a group of young astronomers from  Purple Mountain Observatory, Shanghai Astronomical Observatory, National  Astronomical Observatories and Supercomputer Center of CAS.

The“Pangu  Project” aims  to run a series of extremely large simulations to resolve  the structure formation in the universe dominated by dark matter and  dark energy using China-made supercomputers. This simulation uses nearly  30 billions particles to track the evolution of the matter distribution  in a cubic region of the universe of 4.5 billion light-years on each  side. The series of simulations will help us to understand the complex  physics underlying in the formation and evolution of galaxies , central  supermassive black holes. Moreover, they will  enable Chinese  astrophysicists to make a comprehensive comparison with the wide field  galaxy survey by the LAMOST telescopes, also provide useful mock  catalogues for the Antarctic astronomy at Dome A, Antarctica.
