The Los Alamos Crestone Project is part of the Department of Energy's (DoE) Advanced Simulation and Computing (ASC) program. The main goal of this project is to investigate the use of continuous adaptive mesh refinement (CAMR) techniques for application to problems of interest to the Laboratory. An overview of the astrophysical simulations performed with the SAGE/RAGE codes will be shown here, including asteroid impacts in the deep-ocean, asteroid impacts on the continental shelf (e.g. - Chicxulub - the dinosaur killer), calculations of massive black holes at the galactic center, and calculations of supernova explosions. Examples of these simulations will be shown. We have shown that the SAGE and RAGE codes of the Crestone Project have been very successful products of the DoE's Advanced Simulation and Computing program. It is clear to those performing massively-parallel computations, that the use of thousands of processors in parallel is fundamentally changing the way we think about computer simulations. The Crestone Project codes are fully utilizing each new ASC supercomputer as they become available. The SAGE and RAGE codes are sophisticated Continuous Adaptive Mesh Refinement hydrodynamics codes for large parallel simulations. SAGE and RAGE are becoming useful tools for astrophysical applications. Further research is starting in a wider variety of areas, including cosmological studies with Mike Norman's group at UCSD.
