Talk Abstract: In this talk, we share our vision for real-time generative AI, and the techniques we developed to achieve the fastest LLM inference on GPU ever, with a generation speed of 2500 tokens/s per request. We first showcase our end-to-end stack optimized for minimal latency on AMD hardware, spanning model re-architecting, a single monokernel implementation, along with topology-aware algorithms. In the second part, we focus on one of the defining challenges of megakernels, intra-GPU grid synchronization barriers and reduce/gather primitives. Using a chiplet-aware approach grounded in deep hardware insight, we are able to decrease the overhead from 1.5µs to 600ns.
