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:

# 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:

# 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

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
