During October 2024, Cyzero Kim developed GPU-accelerated POOL2D support for MobileVLM/CLIP inference in the whisper.cpp and llama.cpp repositories. Leveraging C++, Vulkan, and GLSL, Kim designed and integrated a dedicated POOL2D shader and updated the Vulkan pipeline, enabling efficient pooling operations on the GPU. This work reduced inference latency from approximately 2.8 seconds on CPU to 0.7 seconds on GPU, supporting near real-time performance and lowering CPU utilization. Kim also addressed parameter ordering to ensure correct operation sequencing. The engineering demonstrated strong depth in GPU programming and shader development, delivering measurable improvements in throughput and cost efficiency.
