About:
Sleef is a SIMD (Single Instruction, Multiple Data) library designed for high-performance evaluation of elementary functions. It provides vectorized implementations of standard math functions, enabling significant speedups on modern CPU architectures. The library is highly portable and includes optimized routines for various instruction sets including AVX and NEON.

Key Features:

High-performance vectorized math functions
Support for multiple SIMD instruction sets (AVX, NEON, SVE)
Comprehensive set of transcendental functions
Portable across different CPU architectures

Use Cases:

High-performance scientific computing applications
Game engine development requiring fast math operations
Computer graphics and image processing pipelines
Machine learning framework acceleration

Alternatives:

Intel SVML – Sleef is open-source and cross-platform, while SVML is Intel-specific
libm – Sleef provides SIMD-optimized versions of standard libm functions
