We just posted a new course on the freeCodeCamp.org YouTube channel, where instructor Kian Kyars provides a hands-on guide to mastering Distributed Data Parallelism (DDP).

The course shows you how to overcome memory limitations by training models effectively across multiple GPUs. You will explore the theory behind distributed training, including the critical differences between data parallelism and model parallelism, before diving into the DDP workflow. Through a series of practical steps, you will learn to implement manual batch averaging, work with an "All Reduce" sandbox, and utilize DDP hooks to optimize your training processes.

By the end, you will have a deep understanding of the performance trade-offs involved in distributed systems and the expertise to implement them in your own AI projects.

Watch the full course on the freeCodeCamp.org YouTube channel (2-hour watch).
