Detailed Description

SIMD vector of 2 double-precision floating-point real numbers, operations on which use SSE2 instructions available on all recent x86 hardware.

Constructor & Destructor Documentation

VectorSSEDouble()

libint2::simd::VectorSSEDouble::VectorSSEDouble ( 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::VectorSSEDouble::convert_aligned ( T *  a ) const

inline

writes this to a

Note

a must be aligned to 16 bytes

load_aligned()

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

inline

loads a to this
