LLMVisor: A Real-Time Latency Attribution Model for Multi-Tenant LLM Serving

Shuowei Jin, Xueshen Liu, Jiaxin Shan +4

As LLM inference shifts to multi-tenant GPU clusters, co-batching improves throughput but obscures per-tenant usage and limits control. Enabling fractional sharing of the inference…

Dynamic Linear Attention

Xin Wang, Hui Shen, Boyuan Zheng +7

The scalability of Large Language Models (LLMs) to long contexts is fundamentally constrained by the quadratic complexity of standard attention, motivating the adoption of linear a…
