The Fabric Is the Cluster Driver: Cross-Layer eBPF Policies for GPU-CXL Fabrics
Yiwei Yang, Andi Quinn
The paper introduces fabric_ext, an eBPF‑based middleware that lets developers write cross‑layer policies spanning GPUs, DPUs/NICs, and CXL switches, using a semantic movement grap…
Characterizing and Bridging the Diagnostic Gap in eBPF Verifier Rejections
Yusheng Zheng, Zhengjie Ji, Weichen Tao +5
eBPF lets developers run custom programs inside the Linux kernel, where a verifier proves each program safe. However, when the verifier rejects a program, the unclear error makes r…
ActPlane: Programmable OS-Level Policy Enforcement for Agent Harnesses
Yusheng Zheng, Tianyuan Wu, Quanzhi Fu +6
AI agents increasingly run in production through harnesses, the software around the LLM, including an engine that enforces safety and effectiveness policies, e.g., 'run tests befor…
Kops: Safely Extending the eBPF Compilation Pipeline with Native Operations
Yusheng Zheng, Zhengjie Ji, Weichen Tao +4
eBPF safely extends OS kernels in domains such as networking, observability, and security. The safety comes from an in-kernel compilation pipeline where a verifier checks every pro…
Concordia: JIT-Compiled Persistent-Kernel Checkpointing for Fault-Tolerant LLM Inference
Yuhang Gan, Yiwei Yang, Yuyi Li +6
Long-running LLM agents keep valuable state resident on GPUs: KV caches, request schedulers, communication state, and sometimes online adapters. Losing this state after a GPU or co…
CXLMemUring: A Hardware Software Co-design Paradigm for Asynchronous and Flexible Parallel CXL Memory Pool Access
Yiwei Yang, Yusheng Zheng, Kexin Chu +3
CXL-attached memory lets servers add more memory while keeping the standard load/store programming model. The main drawback is latency. CXL memory accesses are too slow for normal…
