This was basically six questions bundled into one.
Start by outlining a declarative Jenkinsfile that defines stages for build, deploy, and test, with parallel execution across hardware/driver matrices. Then dive into orchestration details like sharding, retries, quarantine, and promotion gates, and finish by explaining driver update and rollback strategies with safety checks.
Pro tip: Emphasize idempotency and observability: use unique build tags, capture GPU/driver metadata in artifacts, and implement canary deployments for driver updates to catch regressions early.
Define a declarative Jenkinsfile with stages for build, deploy, and test, using parallel stages to cover multiple hardware and driver configurations. Use Jenkins agents with labels to target specific GPU types.
Implement test sharding to distribute tests across parallel executors, and use retry logic for transient failures. Integrate flaky test quarantine by automatically moving consistently failing tests to a separate suite.
Archive test results, logs, and GPU/driver metadata as artifacts. Set up notifications (e.g., Slack, email) for failures and flaky test detection, and use promotion gates to require manual approval before production deployment.
Describe a process for driver updates: canary deployment to a subset of nodes, automated regression tests, and gradual rollout. For rollbacks, maintain versioned driver packages and use Jenkins jobs to revert to previous stable versions with health checks.
