internal::VectorizedArrayWidthSpecifier< Number > Struct Template Reference

#include <deal.II/base/numbers.h>

Static Public Attributes
constexpr static unsigned int	max_width = 1

Detailed Description

template<typename Number>
struct internal::VectorizedArrayWidthSpecifier< Number >

A helper class specifying the maximal vector length of VectorizedArray for a specified data type Number for the given processor architecture and optimization level.

The value of the maximal vector length is used as default template argument in VectorizedArray, such that VectorizedArray<Number> is equivalent to VectorizedArray<Number, VectorizedArrayWidthSpecifier<Number>::max_width>.

Note

This class is the default implementation for data types for which no vectorization is supported.

Template Parameters

Number

The underlying data type for which one wants to find out the maximal length of hardware supported vectors.
