Fast LLM Post-training via Decoupled and Fastest-of-N Speculation

Rongxin Cheng, Kai Zhou, Xingda Wei +8

Rollout dominates the training time in large language model (LLM) post-training, where the trained model is used to generate tokens given a batch of prompts. This work, SpecActor,…

DiFache: Efficient and Scalable Caching on Disaggregated Memory using Decentralized Coherence

Hanze Zhang, Kaiming Wang, Rong Chen +2

The disaggregated memory (DM) architecture offers high resource elasticity at the cost of data access performance. While caching frequently accessed data in compute nodes (CNs) red…

DecLock: A Case of Decoupled Locking for Disaggregated Memory

Hanze Zhang, Ke Cheng, Rong Chen +2

This paper reveals that locking can significantly degrade the performance of applications on disaggregated memory (DM), sometimes by several orders of magnitude, due to contention…

KunServe: Parameter-centric Memory Management for Efficient Memory Overloading Handling in LLM Serving

Rongxin Cheng, Yuxin Lai, Xingda Wei +2

Serving LLMs with a cluster of GPUs is common nowadays, where the serving system must meet strict latency SLOs required by applications. However, the stateful nature of LLM serving…

BLITZSCALE: Fast and Live Large Model Autoscaling with O(1) Host Caching

Dingyan Zhang, Haotian Wang, Yang Liu +4

Model autoscaling is the key mechanism to achieve serverless model-as-a-service, but it faces a fundamental trade-off between scaling speed and storage/memory usage to cache parame…
