HBFSim: Fast and Faithful Simulation of High-Bandwidth Flash Under Real GPU Execution
Yanpeng Hu, Yiwei Yang, Yuanwu Zhu +3
High-Bandwidth Flash (HBF) places high-capacity NAND beside HBM to relieve the memory-capacity bottleneck of LLM inference, yet its system-level behavior cannot be evaluated before…
When Can Agents Safely Checkpoint, Fork, Restore, and Merge? Exact Checking for Execution Edits
Yusheng Zheng, Xiaoyu Song, Yanpeng Hu +3
Agent runtimes can Checkpoint an execution, Fork it, Restore a checkpoint, or Merge branches without restarting a task. We call these operations execution edits, with Checkpoint re…
gpu_ext: Extensible OS Policies for GPUs via eBPF
Yusheng Zheng, Tong Yu, Yiwei Yang +8
Performance in modern GPU-centric systems increasingly depends on resource management policies, including memory placement, scheduling, and observability. However, uniform policies…
Towards Agentic OS: An LLM Agent Framework for Linux Schedulers
Yusheng Zheng, Yanpeng Hu, Wei Zhang +1
Operating system schedulers suffer from a fundamental semantic gap, where kernel policies fail to understand application-specific needs, leading to suboptimal performance. We intro…
AgentSight: System-Level Observability for AI Agents Using eBPF
Yusheng Zheng, Yanpeng Hu, Tong Yu +1
Modern software infrastructure increasingly relies on LLM agents for development and maintenance, such as Claude Code and Gemini-cli. However, these AI agents differ fundamentally…
bpftime: userspace eBPF Runtime for Uprobe, Syscall and Kernel-User Interactions
Yusheng Zheng, Tong Yu, Yiwei Yang +3
In kernel-centric operations, the uprobe component of eBPF frequently encounters performance bottlenecks, largely attributed to the overheads borne by context switches. Transitioni…
