Talk Title: The CUDA C++ Developer's Toolbox

Description
Getting the most out of your GPU with C++ doesn't require writing custom kernels or manually managing storage for everything! Come learn about the libraries and techniques that make writing CUDA C++ code easier and more performant. Through examples, we'll explore all aspects of writing modern C++ software for GPUs, including heterogeneous memory management, algorithm design, and synchronization.

During this talk, you'll:

• Learn to evaluate when you should use a CUDA library versus writing your own kernel.
• Explore popular CUDA C++ libraries such as Thrust, CUB, and libcu++.
• Understand how you can easily compose different CUDA libraries and your own custom CUDA C++ code together.
• Build intuition about the performance implications of CUDA libraries.
• You'll leave confident about how to select the best tool for the job to accelerate your C++ applications for your unique use cases.

Speaker Bio
Bryce Adelstein Lelbach has spent over a decade developing programming languages, compilers, and software libraries. He is passionate about parallel programming and strives to make it more accessible for everyone.

Bryce is a Principal Architect at NVIDIA, where he leads programming language efforts and drives the technical roadmap for NVIDIA's compute compilers and libraries.

He is one of the leaders of the systems programming language community, having served as chair of the Standard C++ Library Evolution group and the US standards committee for programming languages (INCITS/PL22). He has been an organizer and program chair for many conferences over the years.

On the C++ Committee, he has personally worked on concurrency primitives, parallel algorithms, executors, and multidimensional arrays. He is one of the founding developers of the HPX parallel runtime system. He previously worked at Lawrence Berkeley National Laboratory and Louisiana State University.

Outside of work, Bryce is passionate about airplanes and watches. He lives in Midtown Manhattan with his girlfriend and dog.
