Sweat Capital: Ripping Out TEI for a 27x Embedding Speedup with Go and Custom CUDA

Why I ripped out Hugging Face TEI and built qwen-embed-native, a Go + custom-CUDA embedding engine for Qwen3 that runs fast on sub-H100 hardware.

Why Your RAG Pipeline Doesn't Learn

Your retrieval system reruns the same expensive searches and never tracks which results helped. The retrieval N+1, and how closing the loop changes things.

The Cache Feedback Gap: Why Your Prefetcher Doesn't Learn

Your retrieval cache predicts what to preload and never learns if it was right. The open-loop problem, and what closing the feedback loop unlocks.

Why Your Vector Search Lies

Same query, different results. The floating-point problem that quietly breaks reproducible embeddings, and what bit-exact determinism takes in production.

// The problem with parallel reduction
Thread A: (a + b) + c = 0.30000000000000004
Thread B: a + (b + c) = 0.3
// Same inputs. Different outputs. Nondeterminism.

Why Vector Search is Memory Abuse (And How to Fix It)

Your vector index burns GPU bandwidth chasing pointers through random memory, and a brute-force linear scan often beats HNSW on the GPU.

Random Access Pattern

Cache misses, stalled cores

Sequential Access Pattern

Coalesced reads, saturated bus

Starved Cores: Listening to the Silence Between Epochs

Your H100 sits idle 40% of the time, starved by a data supply chain that can't keep up. Here is the physics, and why the real fix is architectural.
