We intend to reveal the physics of the evolution of the Universe from the pre-formation stage of the first stars to the structure and phenomena of the present solar system through the use of large-scale supercomputing. This project is named ”Computational Observatory” and sixteen research groups from throughout Japanare attempting simulations of four subjects in the different phases of the evolution of the Universe after the dark ages. This project involves finding numerical methods to very hierarchical problems regarding space and time. At the same time, a variety of complex physics should be modeled in the codes that are to be developed. A so-called integrated code for each subject should be developed. The integrated codes, of course, should be checked and improved through comparisons with observational and experimental data. Throughout this project, we would like to analyze not only observational data but also to predict, for example, what new findings we could obtain if we increase the resolution of observation instruments in the future. This project consists a great challenge in computer science in regard to developing a highly integrated system with very hierarchical phenomena..
