A group of Korean scientists has performed two very massive cosmological simulations to study the clustering of galaxies on cosmic time and length scales. These simulations are the biggest ones ever performed. The simulations were done over two months on a supercomputer (Tachyon‐II@KISTI), that was the 37th most powerful supercomputer at the time of this writing. For the simulation, 8,240 CPU cores and 8.7 and 15 terabytes of memory space were used to follow the gravitational evolutions of 216 and 374 billion particles in a cubic box with side lengths of 7,200 h‐1 Mpc and 10,815 h‐1 Mpc, respectively. From the simulation output, we built mock luminous red galaxies (LRGs) in the past light cone space for comparison with future galaxy redshift surveys.
