This module offers an overview of the course and outlines the learning objectives.

Exercise 1: Course introduction

This module details the specialized networking requirements for AI workloads compared to traditional web applications. It covers the specific bandwidth and latency demands of each pipeline stage—from ingestion to inference—and analyzes the "rail-aligned" network architectures of Google Cloud's A3 and A4 GPU machine types designed to maximize "Goodput."

Exercise 1: Role of networking in AI pipeline Exercise 2: AI Hypercomputer networking for ML workloads Exercise 3: Networking for GPU machine types Exercise 4: Quiz Question 1 Exercise 5: Quiz Question 2

This module details strategies for efficiently moving massive datasets into the cloud. It covers the use of the Cross-Cloud Network and Cloud Interconnect to establish high-bandwidth pipelines, and outlines configuration best practices—such as enabling Jumbo Frames (MTU)—to reduce protocol overhead and optimize throughput.

Exercise 1: Overview Exercise 2: Data ingestion over the Cross-Cloud Network Exercise 3: Quiz Question 1

This module details the critical role of low-latency networking in distributed model training. It covers the necessity of Remote Direct Memory Access (RDMA) for gradient synchronization, the benefits of Google's Titanium offload architecture in freeing up CPU resources, and the topology choices required to scale clusters without bottlenecks.
