GPU Bootcamp is an exciting and unique way for scientists and researchers to learn the skills needed to start quickly accelerating codes on GPUs. Held as a virtual event in November, this two-days event will introduce you to available GPU libraries, programming models, and platforms where you will learn the basics of GPU programming through extensive hands-on collaboration based on real-life applications using the OpenACC programming model.

Moreover, you will get hands-on experience on how to use NVIDIA Nsight tools and NVTX to profile your applications. 

Event will start at 9AM CST both days.

Event Format 

The bootcamp will be hosted online in the China Standard Time zone. All communication will be done through Zoom, Slack and email. 


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