FastEEP: Fast Intra-Instance Elastic Scaling for Expert-Parallel MoE Serving

Large-scale expert parallelism (EP) has become the standard deployment configuration for Mixture-of-Experts (MoE) models in production. Meanwhile, the highly dynamic nature of LLM workloads requires providers to continuously adjust serving capacity to match fluctuating demand. Scaling MoE serving cannot be efficiently...

Systematic Exploration of Multi-core Architectures for Efficient LLM Serving using ArguSim

WaferAI-SIM enables simulator-driven co-design of LLM serving strategies and multi-core accelerator architectures, targeting the early design stage in which emerging platforms are not yet broadly available for empirical serving studies, and provides guidance for co-designing hardware architectures and serving strategie...
