2025-07 PaddleCustomDevice monthly summary: Key back-end features were delivered for the Intel HPU backend, including 2D hidden-state representation across fused attention, MLP, and QKV; a transpose flag for QKV weights to support transposed/non-transposed formats; and a use_neox_style switch to toggle between blockwise and pairwise rotary embeddings for Neox-style models. A correctness-oriented fix was implemented to ensure RMS normalization runs before the linear transform in fused block attention by separating RMSNorm from the fused kernels. These changes enhance model fidelity, stability, and flexibility on Intel hardware and broaden support for Neox-style variants. Technologies demonstrated include kernel refactors for fused attention, 2D hidden states, QKV weight handling, RMSNorm sequencing, and rotary embedding strategies.
