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 June, 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. This virtual GPU Bootcamp is organized in collaboration with IIT Kharagpur, National Supercomputing Mission (NSM),, and NVIDIA

This Bootcamp is only for those affiliated with IIT Kharagpur.
