EcoTrace

High-Precision Energy and Emissions Instrumentation

---

v1.6.1 — HuggingFace Integration, CodeCarbon Drop-in API & Metrology Study. Native HuggingFace Trainer callback, CodeCarbon-compatible API layer (EmissionsTracker), Case 08 Metrology & Overhead benchmark, and Zenodo DOI archival integration.

EcoTrace is a lightweight library for granular carbon footprint measurement of Python applications. No configuration files, no background services—just real-time hardware-level transparency.

Real-time monitoring | 50+ Global Zones | AI-powered insights | Zero-configuration

Function-level carbon measurement with real-time monitoring

Core Features in v1.6.0

Latest Release. v1.6.0 introduces automated multi-GPU continuous power tracking, DDR3 RAM hardware detection, a persistent offline disk retry queue for cloud telemetry, and a comprehensive type safety overhaul.

• Automated Multi-GPU Tracking & Aggregation (ecotrace.gpu) — Automatically discovers all available NVIDIA GPUs via NVML (get_all_gpu_info) and aggregates instantaneous power draw at 50ms intervals across active accelerators (get_all_gpu_power_w).
• Comprehensive Multi-Device Telemetry — Startup logs, session summaries, and exported JSON/CSV artifacts now report full GPU array metadata (total GPU count, device models, and combined TDP limit).
• Offline Disk Retry Queue (CloudExporter) — Telemetry payloads are safely persisted to an isolated local disk queue (~/.ecotrace/retry_queue) during network outages or backend 5xx errors, automatically flushing in chronological FIFO order (up to 50 entries) upon reconnection.
• DDR3 RAM Speed Detection (ecotrace.ram) — Evaluates memory clock frequencies (800–2133 MHz) via Linux dmidecode and Windows WMI, applying calibrated DDR3 power factors (0.500 W/GB) for accurate carbon accounting on legacy enterprise hardware.
• Strict Static Type Safety & Diagnostics Overhaul — Complete overhaul eliminating # type: ignore workarounds across core.py, gpu.py, and exporters, achieving clean IDE diagnostics under Pyright/Pylance and hardened exception handling.
• Unified Multi-Device Architecture — Deprecates single-device gpu_index targeting in favor of unified multi-accelerator tracking, emitting a backward-compatible DeprecationWarning if gpu_index > 0 is passed.

Quick Install

pip install ecotrace

Optional extras:

pip install ecotrace[gpu]   # NVIDIA GPU support
pip install ecotrace[ai]    # Gemini AI insights
pip install ecotrace[all]   # Everything

Quick Start

Option 1: Zero-Code Profiling (CLI + Cloud Sync)

Authenticate your terminal once, then profile any script without changing source code:

# 1. Login with your ingestion key from https://ecotracelibrary.com
ecotrace login --key eco_usr_abc123...

# 2. Run your script — metrics automatically stream to your web dashboard!
ecotrace run my_script.py

Option 2: Programmatic Tracking & Cloud Dashboard

Decorate functions for granular instrumentation and stream metrics to your web account:

from ecotrace import EcoTrace

# Connects directly to your hosted account at https://ecotracelibrary.com
eco = EcoTrace(api_key="eco_usr_abc123...", region_code="US")

@eco.track
def my_function():
    # Your heavy processing here
    pass

my_function()

# Export audit-ready reports or check cumulative totals
eco.generate_pdf_report("carbon_audit.pdf")
print(f"Total Carbon Emitted: {eco.total_carbon} gCO2")

Option 3: Carbon Budget Mode

Set a limit and let EcoTrace enforce it:

eco = EcoTrace(
    region_code="TR",
    carbon_limit=5.0,                   # 5 gCO2 budget
    on_budget_exceeded=lambda t, l: print(f"Budget exceeded: {t:.4f}/{l:.4f} gCO2")
)

@eco.track
def training_pipeline():
    ...

training_pipeline()
print(f"Remaining budget: {eco.remaining_budget} gCO2")

Expected Output

When initialized, EcoTrace performs automated hardware detection:

[EcoTrace] INFO: [INFO] EcoTrace instrumentation session initialized (STATIC).
[EcoTrace] INFO: -----------------------------------------------------
[EcoTrace] INFO: Region        : TR (475 gCO2/kWh)
[EcoTrace] INFO: Hardware Logic: 13th Gen Intel Core i7-13700H
[EcoTrace] INFO: Specifications: 20 Cores | 45.0W TDP
[EcoTrace] INFO: Energy Sensor : Boavizta Advanced Estimation
[EcoTrace] INFO: Memory Config : 15.6 GB DDR4
[EcoTrace] INFO: GPU Accelerator: Intel Iris Xe Graphics (15.0W TDP)
[EcoTrace] INFO: -----------------------------------------------------

At process exit, a session summary is printed automatically:

=======================================================
  EcoTrace — Session Summary

  Duration       : 12.34s
  Functions      : 5 tracked

  Budget         : 0.003120 / 5.000000 gCO2 (0.1%) [OK]
  Equivalent     : 0.4 min of LED bulb (10W)

CI/CD Integration

Official GitHub Action

Enforce carbon budgets in your pipeline with our official GitHub Action. Add this to your .github/workflows/ci.yml:

- name: EcoTrace Carbon Gate
  uses: Zwony/ecotrace@v1.6.0
  with:
    budget: '10.0'
    region: 'US'

Manual CLI Integration

You can also run the gate manually:

ecotrace gate --budget 10.0

If total emissions exceed the budget, the gate fails with exit code 1 — preventing carbon-heavy code from being merged.

Why EcoTrace?

• Deep Transparency: Derived from 6,980+ verified manufacturer TDP specifications rather than category averages.
• Fail-Safe Architecture: Guaranteed application continuity even if hardware drivers or API keys are missing.
• Actionable AI: Integrates with Google Gemini to provide specific code optimization advice (optional).

Academic Benchmarks & Empirical Research

EcoTrace includes a reproducible Academic Benchmark Suite designed for peer-reviewed green computing research. Every article in benchmarks/articles/ is auto-generated from real measurement JSONs in benchmarks/results/ by benchmarks/report_generator.py — re-run the generator after new measurements to keep the published numbers in sync.

• Data Engineering: Pandas vs. Polars on 5M Rows — 83.8% carbon reduction via Arrow vectorization (real numbers from this machine).
• Computer Science: Algorithmic Complexity Carbon Scaling — Insertion Sort at $N = 50{,}000$ emits ~3,469× more carbon than NumPy on the same input (the quadratic carbon cliff).
• Cloud Architecture: Web Framework Throughput vs. Carbon — Flask vs. FastAPI under identical load; FastAPI achieves 1.13× speedup and 9.8% carbon reduction (CPU mode).
• Generative AI: LLM Inference Carbon Footprint — Per-token energy and carbon cost of GPT-2 inference (CPU mode; medium/large models require GPU).
• Cloud Architecture: Spatial Carbon Arbitrage across 15 Countries — The same workload in South Africa emits ~73× more carbon than in Sweden (a 99% reduction is achievable by region selection alone).
• Metrology Validation: Empirical Accuracy vs. Intel RAPL Counters — model-vs-hardware validation methodology with honest synthetic-mode fallback for non-Linux systems.
• Machine Learning: PyTorch vs. TensorFlow CNN Training — Carbon per accuracy point analysis (CPU mode; numbers regenerate after each run).
