Pointing the Way for Accelerator Science Community Petascale Project for Accelerator Science and Simulation Panagiotis Spentzouris (project webpage) Fermi National Accelerator Laboratory

The DOE program of scientific discovery relies heavily on particle accelerators, which comprise 14 of the 28 facilities in the DOE twenty-year outlook on Facilities for the Future of Science. The Community Petascale Project for Accelerator Science and Simulation (ComPASS) will develop a comprehensive computational infrastructure for accelerator modeling and optimization. This will advance accelerator computational capabilities from the terascale to the petascale to support DOE priorities for the next decade and beyond.

The SciDAC-1 accelerator project generated a suite of parallel accelerator simulation tools which were applied to important DOE accelerator projects. Under SciDAC-2, these tools will be enhanced to contain new capabilities as needed by HEP projects, such as the ILC, the LHC, the Tevatron, and PEP-II, and for Advanced Acceleration research; NP projects, such as CEBAF and RHIC, the CEBAF and RHIC upgrades, RIA, and an NP electron collider, including ELIC and eRHIC; and BES projects, such as LCLS, NSLS-II, SNS, and upgrades to the APS.

This simulation suite will contain a comprehensive set of interoperable components for beam dynamics, electromagnetics, electron cooling, and advanced accelerator modeling. In each of these areas, the modeling tools require petascale supercomputers and advanced software for making effective use of large, parallel platforms. Consequently, critical to this effort will be the embedded collaborations with the applied mathematics and computer science communities. In the end, high-quality computational tools developed with the best computational physics, applied mathematics, and computer science will be made available to the U.S. particle accelerator community through installation at government laboratories, universities, and industry.
