The RAPIDS Institute (the SciDAC Institute for AI, Computer Science, and Data) is a multi-institution virtual organization funded by the U.S. Department of Energy’s Office of Science Advanced Scientific Computing Research program. RAPIDS brings together experts from national laboratories, universities, and industry to help DOE scientists achieve new scientific breakthroughs on the world’s most powerful supercomputers. The institute focuses on improving the performance and energy efficiency of scientific software, managing and understanding the massive volumes of data produced by modern simulations and experiments, and accelerating discovery through artificial intelligence and machine learning. In addition, RAPIDS works to sustain and improve widely used community software and places a strong emphasis on direct engagement—partnering closely with science teams, facilities, and other institutes to ensure that advanced AI, computer science, and data tools are usable, reliable, and impactful for real scientific applications.
