Phase 7: CI/CD Pipelines for AI Code · 45 min · GitHub Actions · Python · YAML

Parallel Gate Execution

Run independent gates in parallel. Fail fast on dependencies. Reduce CI time from 20 minutes to 5.

Real-world application: Engineers who can optimize CI pipelines with parallel gate execution and dependency graphs demonstrate CI/CD performance engineering skills.

What you will learn

Run quality gates in parallel for faster CI feedback
Design a gate dependency graph to identify independent and dependent gates
Apply fail-fast strategy to stop on first failure in sequential mode
Reduce CI time from 20+ minutes to 5-8 minutes with parallelization and caching

Introduction

Parallel Gate Execution

Objective

Run the parallel gate execution simulator. Observe the 3-layer dependency graph, sequential vs parallel vs parallel+cached execution times, speedup calculations, layer breakdown, and top 5 bottlenecks with optimization suggestions.

Run independent gates in parallel. Fail fast on dependencies. Reduce CI time from 20 minutes to 5.
