OServe: Accelerating LLM Serving via Spatial-Temporal Workload Orchestration

ICML 2026poster

Serving Large Language Models (LLMs) can benefit immensely from parallelizing both the model and input requests across multiple devices, but incoming workloads exhibit substantial spatial and temporal heterogeneity. Spatially, workloads comprise heterogeneous requests with varying compute and memory…

Demystifying Cost-Efficiency in LLM Serving over Heterogeneous GPUs

ICML 2025poster

Recent advancements in Large Language Models (LLMs) have led to increasingly diverse requests, accompanied with varying resource (compute and memory) demands to serve them. However, this in turn degrades the cost-efficiency of LLM serving as common practices primarily rely on homogeneous GPU resourc…

Efficient Pre-Training of LLMs via Topology-Aware Communication Alignment on More Than 9600 GPUs

NeurIPS 2025poster

The scaling law for large language models (LLMs) depicts that the path towards machine intelligence necessitates training at large scale. Thus, companies continuously build large-scale GPU clusters, and launch training jobs that span over thousands of computing nodes. However, LLM pre-training prese…
