# 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 |
|
|
|
|
|
``` |
|
|
Using large file test (~100MB) |

## 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 |
|
