Module simd_dispatch 

Zero-overhead SIMD function dispatch.

This module provides a thin wrapper around simd_native functions, offering a stable public API while simd_native handles the architecture-specific SIMD implementations internally.

EPIC-C.2: TS-SIMD-002

Structs

SimdFeatures

Information about available SIMD features.

Constants

CACHE_LINE_SIZE

Cache line size in bytes (standard for modern x86/ARM CPUs).

PREFETCH_DISTANCE_384D

Prefetch distance for 384-dimensional vectors.

PREFETCH_DISTANCE_768D

Prefetch distance for 768-dimensional vectors (3072 bytes). Calculated at compile time: 768 * 4 / 64 = 48 cache lines.

PREFETCH_DISTANCE_1536D

Prefetch distance for 1536-dimensional vectors.
