The Community Petascale Project for Accelerator Science and Simulation (COMPASS) brings together multiple computational technologies to provide a comprehensive set of computational applications for beam dynamics, electromagnetics, electron cooling, and advanced accelerator modeling. Beam dynamics studies are used to develop understanding of the lifetime limits from beam collisions in colliders. Electromagnetic simulations of cavities are used to optimize cavity shapes for increased accelerating gradient and beam current. Electron cooling computations determine the configuration of cooling systems needed for maximizing luminosity in present and future ion colliders. Simulation and design of plasma-based accelerators is critical for the development of concepts for HEP accelerators beyond the ILC and to develop tabletop electron accelerators for BES and NP projects. Computations are being applied to HEP projects, such as the ILC, the LHC, the Tevatron, and PEP-II, and various plasma-based acceleration experiments; NP projects, such as CEBAF and RHIC, the CEBAF and RHIC upgrades, and RIA; and BES projects, such as LCLS, NSLS-II, SNS, and upgrades to the APS. In each of these areas, the simulation challenges will require adapting our tools to petascale hardware, use of existing parallel software, and the development of new parallel software for making effective use of these large, parallel platforms. Further, we will be developing integrated simulations through use of component technologies. This talk will summarize the state of the application of high-performance computation to accelerator physics.
