|-----------|----------|--------------|
| 1 | 16 GB | 12 GB |
| 8 | 128 GB | 48 GB |
| 32 | OOM | 96 GB |

## 🛠️ Advanced Features

### Distributed Training

```python
# Launch with torchrun
torchrun --nproc_per_node=8 train.py \
    --use-fsdp \
    --fsdp-sharding-strategy full \
    --tensor-parallel-size 1 \
    --pipeline-parallel-size 1
```

### Custom Kernels

```python
from parallel_llm.kernels import fused_attention, parallel_decode

# Use optimized Triton kernels
output = fused_attention(query, key, value, use_flash=True)

# Parallel token decoding
tokens = parallel_decode(logits, num_parallel=64)
```

### Quantization

```python
from parallel_llm.quantization import quantize_model

# Quantize to INT8 or FP8
model = quantize_model(model, precision="fp8")
```
