The free lunch provided by Moore's Law is running out. Still, customers will always want more performance. Parallelism (especially with GPUs) clears a path for software developers to deliver more. This talk offers an exploration of parallelism and artificial intelligence on GPUs with open source tools like Python and Clojure. Audience members will learn how GPU acceleration can boost the performance of AI applications. And everyone will learn how to get up and running with an inexpensive 128-core GPU device, the Nvidia Jetson Nano.
