AB-Sparse: Sparse Attention with Adaptive Block Size for Accurate and Efficient Long-Context Inference

Di Liu, Ruitian Wang, Chen Chen +6

As large language models scale to longer contexts, loading the growing KV cache during attention computation becomes a critical bottleneck. Previous work has shown that attention c…

Justitia: Fair and Efficient Scheduling of Task-parallel LLM Agents with Selective Pampering

Mingyan Yang, Guanjie Wang, Manqi Luo +6

LLM agents, which often comprise parallel inference tasks, are commonly adopted to solve real-world problems. When serving such task-parallel LLM agents in shared GPU servers, the…

Towards High-Goodput LLM Serving with Prefill-decode Multiplexing

Yukang Chen, Weihao Cui, Han Zhao +7

Large Language Model (LLM) serving must meet stringent Service Level Objectives (SLOs) for both the prefill and decode phases. Some existing solutions disaggregate the two phases,…

Towards Resource-Efficient Serverless LLM Inference with SLINFER

Chuhao Xu, Zijun Li, Quan Chen +3

The rise of LLMs has driven demand for private serverless deployments, characterized by moderate-sized models and infrequent requests. While existing serverless solutions follow ex…

Harli: SLO-Aware Co-location of LLM Inference and PEFT-based Finetuning on Model-as-a-Service Platforms

Ao Xu, Han Zhao, Weihao Cui +7

Large language models (LLMs) are increasingly deployed under the Model-as-a-Service (MaaS) paradigm. To meet stringent quality-of-service (QoS) requirements, existing LLM serving s…
