Nvidia Data Parallelism: How to Train Deep Learning Models on Multiple GPUs (DPHTDLM)

Ziele der Schulung

This workshop teaches you techniques for data-parallel deep learning training on multiple GPUs to shorten the training time required for data-intensive applications. Working with deep learning tools, frameworks, and workflows to perform neural network training, you’ll learn how to decrease model training time by distributing data to multiple GPUs, while retaining the accuracy of training on a single GPU.
