I was curious about these libraries a few weeks ago and did some searching. Is there one that's got a clearly dominating set of users or contributors?
I don't know what a good way to compare these might be, other than perhaps activity/contributor count.

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.
How does this compare to fastbase64[0]? Great article, I'm happy to see this sort of thing online. I wish I could share the author's optimism about portable SIMD libraries.

Project mention: XZ: A Microcosm of the interactions in Open Source projects | news.ycombinator.com | 2024-03-30Be direct and put the onus on the reporter/contributor to do more work before you will engage.
e.g., here is Daniel Lemire responding to a very open-ended bug report: https://github.com/lemire/streamvbyte/issues/72
There is something similar in customer service for my SaaS. Customers give horribly vague bug reports. I used to try to divine what they wanted. That way leads burnout. Instead, make them do more of the work.
