## What this evaluates

Evaluates the accuracy of a lightweight analytical framework in predicting GPU latency and dynamic power consumption for AI workloads across different hardware architectures, operating frequencies, and algorithm configurations.

## Datasets

- **EnergAIzer Kernel Database & AI Workloads** — total ?; splits: offline_database (-1), held_out_test (-1); repo https://github.com/kyungmi-lee/energaizer-ispass26-artifact

## Metrics

- `MAPE` **(primary)** — range: percent
  - Mean Absolute Percentage Error: (1/N) * Σ |(Actual - Predicted) / Actual| * 100%. Applied independently to latency and power predictions across workloads or kernels.

## Input / output format

**Input**: Kernel specifications (type, library, tensor shape, precision, operating frequency) or end-to-end workload configurations (model architecture, batch size, sequence length, precision, backend settings).

**Output**: Estimated latency (seconds) and estimated power consumption (watts).

## Scoring recipe

```python
def compute_mape(actual, predicted):
    mask = actual != 0
    return np.mean(np.abs((actual[mask] - predicted[mask]) / actual[mask])) * 100

latency_mape = compute_mape(measured_latency, estimated_latency)
power_mape = compute_mape(measured_power, estimated_power)
avg_latency_mape = np.mean(latency_mapes)
avg_power_mape = np.mean(power_mapes)
```

## Common pitfalls

- CPU kernel launch overhead significantly impacts latency estimation for small kernels, inflating end-to-end errors.
- The model assumes sequential kernel execution and consistent energy efficiency across architectures, failing for overlapping kernels or different memory technologies (e.g., GDDR6 vs HBM).
- Errors exceeding 40% are clipped in reported figures, potentially masking worst-case performance on specific configurations.

## Evidence (verbatim from paper)

> EnergAIzer achieves 11.0% latency and 8.0% power error on the server-grade A100-40GB-PCIE, and 8.8% latency and 8.2% power error on the workstation-grade A10, averaged across all workloads. Our framework captures distinct scaling behaviors of low-utilization (small batch/sequence, left panel) and power-capped (large batch/sequence, right panel) workloads, achieving 6-9% MAPE across frequencies.
