NERSC N-Ways to GPU Programming Bootcamp, Apr-May 2025

NERSC, in collaboration with the OpenACC Organization and NVIDIA, is hosting an N-Ways to GPU Programming Bootcamp for 3 days from Wednesday, April 30 to Friday, May 2. Beginner users in GPU programming are especially encouraged to attend. This is a virtual event. 

The N-Ways to GPU Programming Bootcamp covers the basics of GPU programming and provides an overview of different methods for porting scientific applications to GPUs using NVIDIA CUDA, OpenACC, standard languages, OpenMP offloading, and/or CuPy and Numba. Attendees will also learn how to analyze GPU-enabled applications using NVIDIA Nsight Systems. Throughout the bootcamp, participants are introduced to available libraries, programming models, and platforms through a mix of lectures, labs, and extensive hands-on collaboration based on real-life codes, data, and use cases. 

We will be using Perlmutter GPUs for the Bootcamp. This event has limited capacity, so please apply early. Training accounts for Perlmutter will be provided for non-NERSC users.

Prerequisites

Basic experience with C/C++ or Fortran. No GPU Programming or AI knowledge is required. This event has limited capacity, so please make sure that prerequisites are met before applying.
