Vec

A portable, intuitive toolkit for low-level SIMD programming: works with PowerPC G4 and G5 Altivec, and Pentium 3, Pentium 4 and Itanium MMX/SSE/SSE2/SSE3.

The vec classes make SIMD registers look like small valarrays with all their syntactic sugar. Yet you can still mix and match native intrinsics, fast transcendentals and STL-style functors with equal aplomb.

Amazingly, code compiles on each platform without any object-oriented overhead and is often directly equivalent to intrinsic opcodes!
