4 Commits • 3 Features
Feb 1, 2026February 2026: Delivered three high-impact fusion/quantization features to accelerate large-model training/inference (Qwen-VL fused multi-head rotary embeddings with quantization; Allreduce RMS normalization fusion passes; Qwen-Image horizon fusion with 2-way fused qk_norm). Also implemented targeted bug fixes and test improvements across fusion paths and dispatch logic. Business/tech impact: higher throughput and scalability for Qwen/Qwen-Image models, reduced distributed training overhead, and more reliable test coverage. Technologies demonstrated: kernel fusion, quantization, distributed training optimizations, testing framework enhancements, and robust coding practices.

Nov 1, 2025November 2025 ROCm/aiter focused on delivering a high-impact kernel-level optimization for vision-language inference. Implemented a fused multimodal ROPE RMS kernel for Qwen vision-language models, including new kernel definitions, integration into existing modules, and performance testing to quantify uplift. This work is expected to significantly accelerate inference and reduce latency for multimodal workloads, enabling faster model iteration and deployment.
