Intel oneDNN Acceleration for RISC-V Platform, 2025.6–Present
Contributed to architecture enablement and performance optimization of the Intel oneDNN deep learning library on RISC-V. Integrated JIT compilation based on xbyak_riscv for runtime code generation, developed RVV vectorized kernels with dynamic loop unrolling, and implemented FP16 support for pooling, softmax, and convolution post-operations. Added RISC-V V extension runtime hardware feature detection.

Optimization of Electronic Structure Software (SIESTA), 2025–Present
Optimized NTPoly sparse linear algebra solvers on next-generation ARM heterogeneous platforms. Designed hierarchical memory management to improve HBM/DDR bandwidth utilization, refactored distributed SpGEMM communication to overlap computation and communication, and achieved over 50% floating-point efficiency on single-node large-scale benchmarks.

Neural Network Quantum Chemistry on Sunway Supercomputer, 2024–2025
Participated in large-scale deployment of PyTorch-based scientific machine learning workloads on the next-generation Sunway supercomputer (SW26010-Pro), scaling to up to 100,000 nodes. Investigated runtime anomalies using platform-specific debugging tools and help designed sample rebalancing strategies to improve weak scalability.

"Sunway-NationalLab Cup" China Parallel application Challenge on domestic CPU Final: Porting Blender Rendering Engine to the Next-Generation Sunway Supercomputer, 2022.12
(Role: First author) In this project, I ported the 3D rendering engine Blender to the new-generation Sunway supercomputer, which is equipped with the SW26010-Pro processor. I optimized the parallelization using C++ and the athread runtime library specific to the Sunway platform. I designed a static load balancing scheme, which achieved effective scheduling. I participated in parallelizing the denoising algorithm, achieving up to 45 times speedup. I also led the project defense presentation.

"Sunway-NationalLab Cup" China Parallel Application Challenge on Domestic CPU Preliminary：Optimizing SpMV Algorithm on the Next-Generation Sunway Supercomputer, 2022.7
(Role: First author) In this project, I optimized the SpMV (Sparse Matrix-Vector Multiplication) algorithm of a solver in the OpenFOAM computational fluid dynamics library on the Sunway supercomputer equipped with the SW26010-Pro processor. The system environment was the same as in the final competition. I conducted visual analysis of the competition data using Matplotlib and designed load balancing and vectorization algorithms. The project achieved a speedup of up to nearly 200 times.

National Undergraduate Student Innovation and Entrepreneurship Training Program Project: Research and Application of SLIC Superpixel Segmentation Algorithm Based on Sunway Supercomputer (202210615017), 2022.9
(Role: First author) The project involved porting the SLIC (Simple Linear Iterative Clustering) superpixel segmentation algorithm to the Sunway supercomputer. I proposed the idea, designed a load balancing algorithm. The algorithm utilized continuous shared segments and the large shared mode, implementing heterogeneous parallelism and achieving a speedup of 7 times.
