# HF Jobs Utilities

Utility scripts for testing and benchmarking Hugging Face Jobs environments. These scripts help you verify your Jobs setup and understand the performance characteristics of different GPU flavors.

## Available Scripts

### network-speed-test.py

Test network download speed from within an HF Jobs environment. Useful for:
- Verifying network connectivity
- Comparing download speeds across different GPU flavors
- Benchmarking before running large dataset downloads
- Troubleshooting slow data loading issues

**Features:**
- Pure Python (no dependencies required)
- Fast default test with small file
- Optional `--large` flag for realistic ~100MB test
- Clear metrics (MB/s and Mbps)
- Works locally or on HF Jobs

#### Usage

**Run locally:**
```bash
# Quick test with small file
uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py

# More realistic test with ~100MB file
uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large

# Custom URL
uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py \
    --url https://example.com/testfile.bin
```

**Run on HF Jobs:**
```bash
# Test network speed on L4 GPU
hfjobs run --flavor l4x1 \
    -s HF_TOKEN \
    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large

# Compare across different flavors
hfjobs run --flavor a10 \
    -s HF_TOKEN \
    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large

hfjobs run --flavor h100 \
    -s HF_TOKEN \
    uv run https://huggingface.co/datasets/uv-scripts/jobs-utils/raw/main/network-speed-test.py --large
```

#### Example Output

```

## Why These Utilities?

HF Jobs provides different GPU flavors with varying network configurations. These utilities help you:

1. **Make informed decisions** - Compare network speeds before choosing a flavor
2. **Debug issues** - Verify network connectivity when data loading is slow
3. **Optimize workflows** - Understand if network speed is a bottleneck
4. **Benchmark environments** - Document baseline performance for your use case

## About UV Scripts

This is part of the [uv-scripts](https://huggingface.co/uv-scripts) collection - ready-to-run Python scripts that work with a single `uv run` command. No setup, no virtual environments, just instant execution.
