Detailed Description

SIMD vector of 4 double-precision floating-point real numbers, operations on which use AVX instructions available on recent x86 hardware from Intel (starting with Sandy Bridge processors released in 2011) and AMD (starting with Bulldozer released in 2011).

Constructor & Destructor Documentation

VectorAVXDouble()

libint2::simd::VectorAVXDouble::VectorAVXDouble ( T a )

inline

Initializes all elements to the same value.

Parameters

a	the value to which all elements will be set

Member Function Documentation

convert_aligned()

void libint2::simd::VectorAVXDouble::convert_aligned ( T * a ) const

inline

writes this to a

Note

a must be aligned to 32 bytes

load_aligned()

void libint2::simd::VectorAVXDouble::load_aligned ( T const * a )

inline

loads a to this
