Algorithms and Views

Detailed Description

SIMD versions of the standard range-based algorithms.

An algorithm of this module processes its data with SIMD operations, through eve::wide, with the loop, the alignment and the tail handled by the library. A call looks like its std::ranges counterpart, and the callable receives SIMD values in place of scalars:

std::vector<float> in(1024), out(1024);
eve::algo::transform_to(in, out, [](auto x) { return x * x; });

Two things differ from the standard:

• an algorithm takes ranges, never an iterator pair, which eve::algo::as_range turns into a range;
• the callable is called on eve::wide values of any cardinal, so it is written for a SIMD value and never for a scalar alone.

Required header:

#include <eve/module/algo.hpp>
