Mar 1, 2025March 2025 performance summary for PerfKitBenchmarker. Focused on reliability and accuracy of scaling benchmarks by implementing a daemon-set-aware pod targeting fix. The GetPodOnNode logic now parses the full JSON output from kubectl get pod and filters for pods belonging to the benchmark's daemon-set on the target node, ensuring tests measure the intended workload and avoiding interference from other daemon-sets (e.g., GPU driver). This improves measurement fidelity and confidence in cross-run comparisons.
