Researchers have developed EStream, a novel system designed to enable the efficient execution of Mixture-of-Experts (MoE) large language models on mobile Neural Processing Units (NPUs). EStream addresses the challenges of MoE prefill on mobile devices by separating fixed NPU computations from dynamic MoE decisions, allowing a single compiled expert graph to serve all experts. The system employs expert virtualization to manage model parameters stored in flash memory, loading them into an NPU-addressable arena without impacting performance. Evaluations on a Snapdragon smartphone demonstrated significant speedups and memory reductions compared to existing methods, enabling MoE models with up to 46.7 billion parameters to run effectively. AI
IMPACT This research could significantly expand the capabilities of AI applications on mobile devices by enabling more powerful MoE models to run efficiently.
