# UncheckedIO — 10-Minute Technical Talk **Audience:** IT/Cybersecurity group with programmers and ML engineers **Goal:** Plant the seed, demonstrate the mechanism, invite connections to LLM infrastructure teams --- ## Slide 1 — Open with the hidden thing (0:00–0:45) Lead with an Nsight Systems timeline screenshot. Don't explain it yet. > "This is what happens inside your GPU when a language model processes your request. > The orange is waiting. The GPU costs $30,000 and it's waiting for data." Let the image do the work. This audience will immediately want to know what they're looking at. --- ## Slide 2 — The problem (0:45–2:00) **GPU starvation.** Define it in dollar terms. - Real LLM providers run at 30–50% actual GPU utilization on inference - An 8-GPU H100 cluster costs ~$20/hr to rent - At 40% utilization, $12/hr is wasted — the GPUs are idle waiting for data - LLM providers run hundreds of clusters - The waste is structural and nobody has fixed the root cause --- ## Slides 3–4 — The mechanism (2:00–4:00) Two diagrams, side by side. **Standard pipeline:** ``` CPU tokenizes → Python tensor (pageable memory) → .to("cuda") → kernel buffer → GPU ^--- two OS-mediated copies ``` **UncheckedIO pipeline:** ``` Rust tokenizes in parallel → pinned memory (DMA-accessible) → direct DMA → DLPack → GPU ^--- one copy, no kernel involvement ``` The second diagram has fewer boxes and fewer arrows. That is the entire pitch. Key terms to explain briefly: - **Pinned memory** — memory registered with the OS so the GPU's DMA engine can read it directly - **DMA** — the GPU pulls the data itself, no CPU involvement after the transfer starts - **DLPack** — a standard zero-copy tensor exchange protocol; PyTorch accepts it natively with `torch.from_dlpack()` --- ## Slide 5 — The Nsight demo (4:00–7:00) Show the recorded Nsight Systems timeline from the H100 benchmark run. Both pipelines visible side by side: - Point out the idle gaps (orange) in the standard pipeline - Point out the absence of idle gaps in the UncheckedIO pipeline - Show the DMA transfer lane — this is the "hidden thing" made visible This is the centerpiece of the talk. Expect questions here. That's good. --- ## Slide 6 — The number (7:00–8:00) One slide. No prose. | Hardware | Speedup | |----------|---------| | RTX 3060 (local) | 4.7x | | H100 SXM (cloud) | [Wednesday result] | --- ## Slide 7 — Market fit (8:00–9:00) - This is infrastructure every LLM provider needs - Built as an open-core library: PostgreSQL→Arrow is Apache 2.0 and already on PyPI - GPU ingestion pipeline is the commercial layer - AMD ROCm support (MI300X) is next — providers are actively evaluating MI300X to escape H100 pricing Don't pitch deal specifics. This slide plants the seed. --- ## Slide 8 — The close (9:00–10:00) > "I'm looking for connections to ML infrastructure teams and LLM providers. > If you know someone building at that layer, I'd appreciate an introduction." Direct. Not desperate. Leave room for questions. --- ## Notes **What NOT to do:** - Don't go deep on the Rust implementation — the visual is the hook, not the code - Don't mention the PostgreSQL→Arrow piece — it's a distraction in this context - Don't volunteer that it's unfinished — if asked, "it's in active development and the core mechanism is proven" **For the well-connected engineer (separate talk, two weeks out):** Don't reuse this version. Prep a deeper, tailored pitch after seeing what questions come up here. **For the NVIDIA contact:** Wait until after the H100 benchmark. Send the Nsight trace + one paragraph. Leading with a measurement is different from leading with a claim.
