The Cache Feedback Gap: Why Your Prefetcher Doesn't Learn
Server push and predictive caching have existed for years. Why do caches still waste bandwidth on data nobody uses?
Read ArticleFrom the Kernel.
Technical deep-dives on GPU memory, sorting, and deterministic compute.
Solving N+1 with Bidirectional Hints
DataLoader batches requests. HINT predicts them. Here's how to eliminate the N+1 problem at the protocol level.
Read ArticleWhy Graph Traversal is Bullying Your HBM3e
The hardware is screaming for linear reads, but HNSW gives it random noise. We analyze the physics of memory coalescing and why bandwidth-bound sorting is the only way to respect the memory bus.
Random Access Pattern
Cache misses, stalled cores
Sequential Access Pattern
Coalesced reads, saturated bus
The Butterfly Effect in Your FPU: Why Parallel Math is Chaos
Taming the nondeterministic nature of parallel floating point. In regulated sectors like HFT and Defense, 'approximate' results are a liability. We explore the engineering challenges of achieving 100% reproducibility.
// The problem with parallel reduction
Thread A: (a + b) + c = 0.30000000000000004
Thread B: a + (b + c) = 0.3
Thread B: a + (b + c) = 0.3
// Same inputs. Different outputs. Nondeterminism.
Starved Cores: Listening to the Silence Between Epochs
Latency isn't just about search speed; it's about the silence when the GPU waits for data. An analysis of DataLoader bottlenecks and how predictive caching (HINT) keeps the silicon singing.
