Xiekeke contributed to the PaddlePaddle/Paddle repository by engineering core compiler and GPU optimizations for deep learning workloads. Over four months, Xiekeke developed features such as Softmax and reduction optimizations in CINN, introducing tiling strategies and configuration refinements to improve throughput and resource efficiency. Their work included refactoring synchronization logic with cooperative CUDA launches, standardizing data structures, and simplifying the build system by removing external dependencies like Abseil. Using C++, CUDA, and cmake, Xiekeke also addressed GPU safety by fixing out-of-bounds errors and expanded mixed-precision support. The work demonstrated depth in performance tuning, code maintainability, and numerical robustness.

Apr 1, 2025Monthly summary for PaddlePaddle/Paddle (2025-04): Delivered CINN improvements focusing on synchronization, kernel launches, and data structure standardization to enhance stability, scalability, and performance. Implemented cooperative launch logic and RequiresCooperativeLaunch to replace semaphore-based cross-block reductions, simplifying grid reduction synchronization and improving determinism. Optimized CUDA launch bounds handling (max_threads_per_block, min_blocks_per_sm) to boost kernel launch robustness and occupancy, and standardized hash map usage across CINN components to paddle::flat_hash_map for consistency and maintainability. These changes reduce runtime risk in large-scale GPU deployments, streamline maintenance, and demonstrate strong proficiency in CUDA programming, cooperative_groups, and modern C++ practices.

Feb 1, 2025February 2025: Delivered a targeted Softmax optimization in CINN within PaddlePaddle/Paddle, leveraging a bucket splitting strategy and tiling refinements to boost performance for both static and dynamic shapes. Refactored configuration to introduce the reduce_inner_num parameter, enabling finer control over inner reductions and broader applicability across workloads. These changes reduce Softmax bottlenecks and improve throughput and resource efficiency, laying groundwork for broader CINN optimization. No major bugs fixed in scope this month; focus was on performance engineering and architectural refinements. Technologies demonstrated include CINN optimization, tiling strategies, configuration management, and performance tuning, contributing to higher throughput for PaddlePaddle deployments.
