Fabiao Miao developed and optimized backend features for the PaddlePaddle/PaddleCustomDevice repository, focusing on Intel HPU integration and performance improvements for large language model inference. Over seven months, he implemented custom operators and kernels in C++ and Python, such as step generation and prefix caching, to accelerate sequence processing and reduce latency. His work included robust bug fixes in memory management and post-processing logic, as well as automation scripts for benchmarking and reproducible performance analysis. By refactoring operator logic and enhancing test coverage, Fabiao ensured reliable, maintainable code that improved throughput and stability for HPU-based deep learning deployments.

Oct 1, 2025Month: 2025-10 — PaddleCustomDevice delivered a performance-focused enhancement for Llama inference on the Intel HPU backend by adding prefix caching. This work targets long-context attention bottlenecks, enabling faster responses and better hardware utilization for customers deploying Llama with Intel HPU. The feature introduces conditional inclusion of attention masks based on causality in fused_sdpa_proj_t.cc and adds a dedicated prefix caching workflow with sequence-length calculations and padding strategies in prepare_block_metadata.cc. The change is tracked under commits for #2086, including 7f594d0f99b69cac15f8b516d273aaa901f51641. Overall, this delivers tangible business value by reducing latency and increasing throughput in production inference pipelines.

Aug 1, 2025August 2025: Delivered a robust recovery bug fix for the Intel HPU Step Paddle Function in PaddleCustomDevice, addressing edge cases and improving reliability. The changes removed an unused environment variable, updated total batch calculation to use encoder count directly, and tightened block-management logic with improved tie-breaking for maximum bid when used block numbers are equal. The work is tracked under commit 9cf922aab337af510db2c38780f800eb2265748c (#1901). Impact: higher stability for HPU-based training/inference, reduced risk of block-related failures, and clearer, traceable code changes.

Mar 1, 2025March 2025 monthly summary for PaddlePaddle/PaddleCustomDevice focused on Intel HPU backend enhancements and reliability improvements. Delivered a new One-Hot operation kernel for Intel HPU with support for int32/int64 inputs, including kernel implementation, type registrations, and unit tests. Fixed reliability of reduce_prod and reduce_mean by refactoring ProdKernel to include a reduce_all parameter and updating tests, removing outdated skips and redundant test classes to improve stability. These efforts reduce integration risk and lay groundwork for broader HPU support and performance improvements.
