Quick Start

Requirements

• C23 Clang

Clone, Build, & Run

git clone https://github.com/jspingu/threefold.git
cd threefold
make -j$(nproc)
./out

Vectorization Options

By default, vectorized function variants are built for all supported SIMD extensions on the target architecture and called through dynamic dispatch.

To build a tailored binary with static dispatch instead:

CFLAGS="-march=native" VECTORIZATION="static" make -j$(nproc)

Supported extensions:

• x86: SSE2, AVX2, AVX512F
• ARM: NEON (v7), SVE
