Detailed Description

An interface to a type with floating point values.

By setting suitable compile-time defines oen can set the length, accuracy and implementation of the vector. The vector length has to be a multiple of WID, which is 4 in Vlasiator. It also cannot be larger than WID*WID or 16. Thus 4, 8 or 16 are now supported. Currently implemented vector backends are:

VEC4D_AGNER

• Double precision
• Vector length of 4
• Use Agner's vectorclass with AVX intrinisics

VEC4F_AGNER

• Single precision
• Vector length of 4
• Use Agner's vectorclass with AVX/SSE2 intrinisics

VEC8F_AGNER

• Single precision
• Vector length of 8
• Use Agner's vectorclass with AVX intrinisics
