Multi-GPU Programming Bootcamp
May 6 • 09:00 – May 7 • 14:30 CEST
Overview
Welcome to the Multi-GPU programming bootcamp!
Scaling applications to multiple GPUs across multiple nodes requires one to be adept at programming models and optimisation techniques, and proficient at performing root-cause analysis using in-depth profiling to identify and minimise bottlenecks.
Topics on GPU programming covers single node multi-GPU (P2P) and multi-Node multi-GPU (GPU Direct) programming, the NVIDIA Collectives Communications Library (NCCL), and the NVSHMEM, which is a parallel programming interface based on OpenSHMEM that provides efficient and scalable communication for NVIDIA GPU clusters).
The Multi-GPU Programming Bootcamp covers step-by-step ways to improve application performance using cues from profilers and provides an understanding of the underlying technologies and communication topology needed to leverage powerful NVIDIA® libraries to extract more performance from the system.
Prerequisites
- Experience with C/C++, NVIDIA CUDA®, MPI
