Architecture Specific Kernel Code Generation And Selection

via “architecture-specific kernel code generation and selection”

Official inference framework for 1-bit LLMs, by Microsoft. [#opensource](https://github.com/microsoft/BitNet)

Unique: Implements automatic kernel code generation pipeline that produces architecture-specific optimizations at build time, then selects fastest variant at runtime; uses I2_S/TL1/TL2 quantization scheme abstraction to decouple algorithm from hardware implementation

vs others: More portable than hand-optimized kernels because generation is automated; faster than generic C++ implementations because generated code uses target-specific SIMD instructions (AVX2, NEON) with compiler-level optimizations
