Abstract:
Are video games a waste of time? Your parents might say yes, but many scientists would strongly disagree. The same technology that makes games so fast and fun is now helping solve some of the hardest problems in science. The key is the Graphics Processing Unit, or GPU. This special chip is built to handle huge numbers of calculations at the same time, which is perfect for drawing game graphics in fractions of a second. Because GPUs can do many tasks in parallel, they are now taking over from traditional computer processors for most heavy number crunching. They can do more work, much faster, while using less energy. Someday, quantum computers might be even more powerful, but until then, GPUs are leading the way. They are not just for video games anymore, they are driving progress in artificial intelligence, Earth science, and many other fields. In this talk, you will see how GPUs have sped up computer models of the atmosphere by as much as 100 times. These ultra fast simulations are helping scientists and engineers develop new ways to keep people in big cities safe from threats in the air.
