Inside Claude Code’s Query Loop: From a Simple While Loop to an Industrial‑Grade Agent Engine

This article dissects Claude Code’s 1729‑line queryLoop, explaining its four‑layer call chain (ask → QueryEngine → query → queryLoop), the async‑generator core that streams model output, how tool calls are handled in parallel, the explicit state object, and the many error‑recovery paths that make the loop production‑ready.

Why a Mathematically Free Matrix Transpose Is 10× Slower on CPUs

A naive 1024×1024 matrix transpose can be ten times slower than an optimized version because the CPU sees memory as a linear address space, and row‑major layout combined with cache‑line granularity makes column‑wise accesses incur massive cache misses, which can be eliminated with blocking, prefetching and SIMD techniques.
