Yusheng Zheng云微

Ph.D. Candidate in Computer Science and Engineering at UC Santa Cruz

Building programmable and observable runtimes for AI infrastructure.

My research spans GPU runtime and policy mechanisms, distributed-training performance diagnosis, Linux extensibility, and system support for autonomous agents. I am expected to graduate in 2027 and am a Research Scientist Intern (AI Infrastructure) at ByteDance in Summer 2026.

Expected Ph.D. 2027 Santa Cruz · San Francisco Bay Area

Research

Selected Systems

Systems are the primary unit of my work: each combines a concrete mechanism, an implementation, and evaluation or downstream use.

SysOM-AI

Co-first author · research design & prototype

Continuous cross-layer diagnosis for production AI training, combining CPU stack profiling, GPU kernel tracing, and NCCL instrumentation with less than 0.4% overhead.

Validated by Alibaba collaborators across 80K+ GPUs; 94 confirmed production issues diagnosed.

bpftime

Creator / lead maintainer · OSDI 2025

A userspace eBPF runtime and verified application-extension framework combining verification, isolation, and dynamic instrumentation without application recompilation.

1.5K+ GitHub stars, active external users, and downstream integrations in the eBPF ecosystem.

gpu_ext

First author · GPU runtime research

A programmable policy runtime spanning the Linux GPU driver and device, with verified hooks and device-side execution for scheduling, memory, and observability policies.

Up to 4.8× throughput improvement and 2× lower tail latency on evaluated AI workloads.

AgentSight

Creator / lead maintainer · agent runtime observability

System-level boundary tracing that correlates LLM and agent activity with process, file, network, and OS effects without requiring application SDK instrumentation.

Less than 3% average overhead; integrated into Alibaba Cloud Linux 4 Agentic Edition (ANOLISA).
