CE8125 - Connect with the Experts: Ease-of-Programing vs Performance – A Comparison of Parallel Computing Models

Session Speakers
Session Description

We will give a brief overview of programming with OpenACC and CUDA showing the performance trade-offs vs ease-of-use. We will answer your questions on OpenACC and CUDA's four memory approaches {memory copies, pinned memory copies, unified memory, and oversubscribed unified memory} and compare ease-of-programming against performance on several common analytics, using library calls and a custom kernel. The goal is to give users an understanding of what gains could be achieved versus how much effort is required.
