Enabling Large Scale Simulations for Particle Accelerators

International high-energy particle physics research centers, like CERN and Fermilab, require excessive studies simulations to plan for the upcoming upgrades of world's largest accelerators, design future machines given technological challenges tight budgetary constraints. The Beam Longitudinal Dynamics (BLonD) simulator suite incorporates most detailed complex phenomena in field longitudinal beam dynamics, required providing extremely accurate predictions. Modern dynamics dictate longer, larger numerous simulation draw meaningful conclusions that will drive baseline choices daily operation current projects. These are time consuming, would be impractical perform without a High-Performance Computing oriented framework. In this article, at first, we evaluate highly-optimized distributed version BLonD. We combine approximate computing techniques, leverage dynamic load-balancing scheme relax synchronization improve scalability. addition, employ GPUs accelerate implementation. highly optimized supercomputing system demonstrate speedups more than two orders magnitude when run on 32 GPU platforms, w.r.t. previous state-of-art. By driving wide range new studies, proposed high performance forms an invaluable tool accelerator physicists.
