#SIMD

You have a sorted array. Need to search it. `std::lower_bound`: O(log n), predictable, robust. This is the default solution. But my industry experience breeds skepticism. Every few months, a new paper

Llama.cpp's PR #22423 landed a kernel fusion for RMS_NORM + MUL in the ggml CPU backend a few weeks ago. The speedup: 1.60×. Consistently. Across dimension sizes, thread counts, even hardware variatio

I manually unrolled a byte-counting loop with four independent accumulators — the textbook ILP optimization — and it ran 2.08x *slower* than the plain loop. The plain loop that GCC had quietly autovec

The RP2350 has a feature most embedded developers ignore. Two Cortex-M33 cores at 150 MHz, 520 KB of SRAM, $0.80 in quantity — and buried in the ISA, packed arithmetic instructions that process four 8
