ReliefServe: Relieving GPU Pressure in Multi-Model Serving via Selective CPU Escape

The key is that migrating CPU-tolerant models to CPU during bursts can reduce overall GPU interference more than the local slowdown incurred, thus protecting performance-critical GPU models even with slower CPU execution.

DScale: Scaling Block-Diffusion Speculative Decoding with Adaptive Verification

C cumulative ablations show that adding the three mechanisms successively increases geometric-mean throughput, while budget adjustment improves accepted-token retention, and DScale is presented, preserving drafter architecture, weights, and full draft length.

BrownoutMoE: Structure-Aware Expert Grouping for Efficient and Accurate LLM Web-based Services

Inspired by the brownout paradigm in service computing, BrownoutMoE reorganizes experts into groups to improve utilization and system efficiency while maintaining service quality and introduces a grouping-consistent distillation process to produce deployable models that are compatible with standard inference pipelines.

Movable-Antenna Assisted Energy Minimization in UAV-Enabled Mobile Edge Computing Systems

This paper explores a movable-antenna (MA) assisted energy minimization scheme in an uncrewed aerial vehicle (UAV)-enabled MEC system, where a UAV equipped with an MA array serves as an edge server to process tasks offloaded from terrestrial consumer electronics devices.

CoCoScale: Leveraging Layer-wise Scaling to Unlock the Potential of Online LLM Serving

CoScale is proposed, a layer-wise dynamic scaling mechanism that selectively expands the parallelism of hot layers onto idle resources reclaimed from underutilized devices, enabling elastic data parallelism without altering model architectures or adding hardware overhead.

DynoPipe: Heterogeneous Edge-Cloud LLM Serving with Dynamically Orchestrated Pipeline Boundaries

Large language model (LLM) deployment at the network edge faces a fundamental paradox: applications require full-scale models for sophisticated reasoning, yet edge devices impose severe resource constraints across computation, memory, and network. Existing approaches fail to effectively orchestrate resources across the...
