Worked on performance optimization for the jeejeelee/vllm repository, focusing on accelerating CPU-bound attention computations. Developed and integrated a fast vectorized exponential function using Arm Optimized Routines within the AttentionMainLoop, targeting improved throughput on ARM-based hosts. The approach leveraged C++ and advanced vectorization techniques to enhance inference and training speed, while maintaining code portability and maintainability. Collaborated with Arm and Ubuntu maintainers to ensure alignment with platform-specific best practices. The work demonstrated strong skills in CPU optimization, performance engineering, and cross-team communication, directly supporting scalable ARM deployments and contributing to the repository’s broader performance and engineering goals.
