PROFILE
Lingfeng.qiu
Worked on the FlagOpen/FlagGems repository to enhance the MTHREADS backend for machine learning workloads, focusing on both functionality and stability. Developed and optimized low-level matrix multiplication kernels, including mm, addmm, and bmm, using C++ and CUDA to improve performance and compatibility. Addressed datatype handling in matrix operations to ensure reliable Qwen3-8B model inference, preventing type mismatches and runtime errors. Implemented explicit logic to skip unsupported benchmarks, reducing deployment risk and improving maintainability. Demonstrated expertise in backend development, tensor operations, and performance optimization, delivering features that support broader model compatibility and smoother multi-threaded compute workflows.

Sep 1, 2025September 2025 (FlagOpen/FlagGems): Delivered Qwen3-8B model compatibility for the matrix multiplication (mm) operation by aligning the output datatype of matrix C. This prevents type mismatches across configurations and enables reliable Qwen3-8B inference. Major fix implemented via commit d7fd52f95e57206347f4c230da9605780aca1c7f ([MTHREADS] Fix mm op to support Qwen3-8B), reducing runtime errors and smoothing deployment. Business impact includes faster time-to-value for Qwen3-8B workloads and a solid foundation for broader model support. Demonstrated skills in low-level numeric ops, datatype management, and multi-threaded compute optimizations.
