LightX2V supports distributed parallel inference, enabling the use of multiple GPUs for inference. The DiT part supports two parallel attention mechanisms: **Ulysses** and **Ring**, and also supports **VAE parallel inference**. Parallel inference significantly reduces inference time and alleviates the memory overhead of each GPU.

## DiT Parallel Configuration
## DiT Parallel Configuration
DiT parallel is controlled by the `parallel_attn_type` parameter and supports two parallel attention mechanisms:
### 1. Ulysses Parallel
