PPPL’s computational physics staff makes use of powerful supercomputers on the Princeton University campus as well as the extraordinary powers of national supercomputers for complex, mission-critical computations.
Stellar, a computing cluster at the University’s High-Performance Computing Research Center, allows our computational physicists to test and fine-tune computer codes before running them on national supercomputers, where time is limited. These codes are used to model experiments aimed at developing fusion as a safe, clean, and plentiful method of generating electricity and predicting disruptions that can halt fusion reactions and damage fusion devices. PPPL codes are used throughout the fusion world.
Another computing cluster at Princeton University, called Traverse, is equipped with graphics processing units (GPUs) that facilitate artificial intelligence for codes that use GPUs. The computational physics community at PPPL thus uses the most powerful and sophisticated supercomputers, to enable our mission of creating energy from fusion for a virtually inexhaustible power supply for all humankind.
