walberla::field::AllocateAligned< T, alignment > Class Template Reference

Detailed Description

template<typename T, uint_t alignment>
class walberla::field::AllocateAligned< T, alignment >

Aligned Allocation strategy for Fields.

Template parameters:

• T type that is stored in field
• alignment the beginning of each row of the field is placed such that the memory address 'a' of each row fulfills: a % alignment == 0 alignment has to be a power of 2
