From SIMD Wrappers to SIMD Ranges - Part 1 Of 2 - Denis Yaroshevskiy & Joel Falcou - C++Now 2025
---

Basic std::simd was voted into the working draft in November. But there are active ongoing discussions, with a slew of proposals still coming.
One of those proposals is probably a ranges library. In the eve library we already have one. We implemented a lot of algorithms in abstractions not dissimilar to the ones being standardized.
We’d like to share our experience.

In the first part of the talk we will go through a few algorithms at a high level: memcmp, reduce, min_element, copy_if.

In the second half, armed with that knowledge, we will go through different problems, their possible solutions and tradeoffs, which arise when designing a SIMD ranges library.
