  You can use https://github.com/simd-everywhere/simde if you like. In general portable SIMD libraries are of limited utility because having different primitives available on different architectures means that you should approach problems differently. That is to say, in many cases using any portable SIMD API to solve your problem means leaving 200% speedups on the table on at least one of your top 3 targets.

  From gh-topics/SIMD:

  SIMDe: https://github.com/simd-everywhere/simde :

  > The SIMDe header-only library provides fast, portable implementations of SIMD intrinsics on hardware which doesn't natively support them, such as calling SSE functions on ARM. There is no performance penalty if the hardware supports the native implementation (e.g., SSE/AVX runs at full speed on x86, NEON on ARM, etc.).

  > This makes porting code to other architectures much easier in a few key ways:

  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 note that SIMDe doesn't have RISC-V support yet (but it does support Loongson LoongArch):

  There are still a ton of things to do to get the Debian riscv64 port going too:

  > low level code that can run on multiple hardware architectures

  I thought SIMD Everywhere was a pretty interesting project for that, lets you write x86 SSE/AVX code and run it on non-x86 architectures:

  > architecture-specific features such as SSE/AVX which is not portable.

  I don’t have hands-on experience, but somewhere on HN I saw this: https://github.com/simd-everywhere/simde If starting a new cross-platform project today, I would try that library first, before doing the usual intrinsics.
