Bolshoi Simulations
There are two Bolshoi simulations: Bolshoi uses WMAP cosmology and BolshoiP is for the Planck cosmology. Both were produced with the ART N-body code. The simulations use 250Mpc/h computation boxes and 2048^3 particles. Force resolution (size of the smallest cell) 1kpc/h (proper). More details of the simulations are given here.
