A dense, data-rich exploration of CPU-based matrix transpose optimizations, showing memory-latency bottlenecks, block-based strategies, and SIMD/AVX2/AVX256 approaches with concrete performance metrics across various matrix sizes, culminating in a highly optimized Vec256Buf method.
A peer‑reviewed AVX‑512 SIMD algorithm dramatically accelerates integer-to-decimal string conversion, delivering up to ~1.4 GB/s throughput and 2–4x speedups over std::to_chars, with a dual‑variant (homogeneous and heterogeneous) design plus a lightweight dynamic selector that minimizes overhead across varied datasets.
A data-rich benchmark of Boost.Container’s segmented iterators shows substantial, compiler-dependent performance gains over non-segmented paths (up to ~17x in some cases), with mixed results from inner-loop unroll hints and stdlib implementations.
A data-rich historical analysis of x86 SIMD from MMX to AVX-512, emphasizing the engineering tradeoffs, competitive dynamics, and the resulting fragmentation and partial unification efforts that shape today’s vector landscape.
