PLoRA: An NDP-Enhanced Pooled-Memory System for Cost-Efficient Multi-LoRA Serving

Zhongkai Yu, Ohm Rishabh Venkatachalam, Zheng Wang +9

Multi-LoRA serving is how one base model becomes thousands of specialized variants, one adapter per user, task, or agent, and the deployments can hold 1000-plus adapters. Serving t…

FlashCP: Load-Balanced Communication-Efficient Context Parallelism for LLM Training

Zheng Wang, Eric Liu, Linan Jiang +5

Context parallelism (CP) is essential for training large-scale, long-context language models, as it partitions sequences to reduce memory overhead. However, existing CP methods suf…

ChipMATE: Multi-Agent Training via Reinforcement Learning for Enhanced RTL Generation

Zhongkai Yu, Yichen Lin, Chenyang Zhou +12

Existing API-based agentic systems for RTL code generation are fundamentally misaligned with industrial practice: they assume a golden testbench is available at generation time, re…

FlashEvolve: Accelerating Agent Self-Evolution with Asynchronous Stage Orchestration

Zhengding Hu, Mingge Lu, Zhen Wang +8

LLM-based evolution has emerged as a promising way to improve agents by refining non-parametric artifacts, but its wall-clock cost remains a major bottleneck. We identify that this…
