About the role#
This internship is part of the AGI Computing Lab. You will research next-generation memory solutions for AI workloads, including HBM, DRAM, and CXL memory expansion. Working with Samsung CXL memory expanders and NVIDIA GPUs, you will analyze how agentic AI workloads stress memory systems. Your findings will directly influence future memory product architecture design.
What you'll do#
- Build runtime adapters and a trace record/replay harness for AI agent frameworks.
- Develop micro-kernel and end-to-end agent workload benchmarks that stress CPU, memory, storage, and accelerator subsystems.
- Profile agent workloads with perf, eBPF, PMUs, and NVML/DCGM to break down per-turn latency and memory bandwidth usage.
- Measure host DDR5, GPU HBM, and CXL.mem bandwidth and latency across Intel Xeon and AMD EPYC servers.
- Evaluate multi-agent KV-cache sharing and CXL memory expansion on Samsung CXL expanders.
- Build an initial memory tiering cost model for long-running MoE agent workloads.
- Present findings in weekly team meetings and deliver a final report and presentation.
- Complete other responsibilities as assigned.
What you'll need#
- Currently pursuing a PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related field.
- Strong programming skills in Python and C/C++ within a Linux environment.
- Solid understanding of computer architecture, specifically CPU caches, memory hierarchy, and NUMA.
- Experience with performance profiling tools such as perf, eBPF, VTune, or Nsight.
- Preferred: Hands-on experience with LLM serving frameworks like vLLM or SGLang.
- Preferred: Familiarity with HBM, CXL, or heterogeneous memory systems.
- Preferred: Experience with AI agent frameworks or benchmark development.
Location & details#
- Location: San Jose, California, United States.
- Modality: On-site.
- Term: Summer 2027.
- Status: Full-time and paid internship.
