- Add PixArtTensorParallelismPlanner for both PixArt-Alpha and PixArt-Sigma models - Implement column-wise parallelization for attention Q/K/V projections and feed-forward - Add comprehensive example script in examples/parallelism/run_pixart_tp.py - Update support matrix to show TP support for PixArt models - Support standard BasicTransformerBlock architecture with self/cross-attention
- Add verify_pixart_layers.py for checking PixArt model linear layers - Supports both PixArt-Alpha and PixArt-Sigma pipelines via environment variable - Prints all linear layers across all transformer blocks for layer plan verification - Simple, focused script without over-engineering
- Correct rebase conflict resolution error that incorrectly set CogVideoX 1.5 TP support to ✖️ - Main branch already had CogVideoX 1.5 TP support as ✅, should preserve during rebase
