SIMD Library for Evaluating Elementary Functions, vectorized libm and DFT

Project mention: The Case of the Missing SIMD Code | news.ycombinator.com | 2023-06-08

I'm the main author of Highway, so I have some opinions :D Number of operations/platforms supported are important criteria.
A hopefully unbiased commentary:
Simde allows you to take existing nonportable intrinsics and get them to run on another platform. This is useful when you have a bunch of existing code and tight deadlines. The downside is less than optimal performance - a portable abstraction can be more efficient than forcing one platform to exactly match the semantics of another. Although a ton of effort has gone into Simde, sometimes it also resorts to autovectorization which may or may not work.
Eigen and SLEEF are mostly math-focused projects that also have a portability layer. SLEEF is designed for C and thus has type suffixes which are rather verbose, see https://github.com/shibatch/sleef/blob/master/src/libm/sleef... But it offers a complete (more so than Highway's) libm.

Project mention: Java Matrix Algebra Library | /r/math | 2023-05-05

I worked on a similar hobby project for a while! Even if no one is ever going to use it, it was still a lot of fun to write. Obviously the language is different, but here is my implementation of eigenvalue/eigenvector finding.
