| 8 | +# Examples & Use Cases |
| 9 | + |
| 10 | +Discover what's possible with Forgather's template inheritance and distributed training capabilities. |
| 11 | + |
| 12 | +## 🚀 Distributed Pipeline Parallelism |
| 13 | + |
| 14 | +### Large Model Training on Consumer Hardware |
| 15 | + |
| 16 | +Successfully training 7B parameter models across multiple RTX 4090 cards using various pipeline schedules: |
| 17 | + |
| 18 | +- **Zero-Bubble Pipeline**: Maximizes GPU utilization with minimal idle time |
| 19 | +- **Interleaved 1F1B**: Balanced approach with good memory efficiency |
| 20 | +- **Standard 1F1B**: Most memory-efficient option for resource-constrained setups |
| 21 | + |
| 22 | +### Real Hardware Testing |
| 23 | + |
| 24 | +Current development uses a 6x RTX 4090 setup, with 4 cards sufficient for 7B models. The system demonstrates that consumer hardware can handle serious model training when properly orchestrated. |
