High Performance Computing for Accelerator Design and Optimization

Scientists use computer simulations to understand and optimize current and future particle accelerators. Advances in particle accelerator technology will require simulations that are both more complex and more accurate than any simulations to date.

ComPASS4 research is funded by the U.S. Department of Energy’s Scientific Discovery through Advanced Computing (SciDAC) program. ComPASS4 will adapt and develop many intertwined pieces of software to efficiently exploit the next generation of high-performance computing architectures to perform accelerator simulations. To that end, we have formed a partnership between physics teams at Fermilab and the University of California, Los Angeles (UCLA) and applied mathematics and computer science teams at Argonne National Laboratory, Berkeley Laboratory and UCLA to prepare our particle-in-cell (PIC) software to have higher fidelity and to take advantage of new computing hardware.

Throughout the research program, the software we develop will be used by project members and the particle physics community to simulate and optimize current and future particle accelerators.
