Thanks for your interest in the library.
Here is a godbolt example: https://godbolt.org/z/bEGd7Tnb3 Here is a bunch of simple examples: https://github.com/jfalcou/eve/blob/fb093a0553d25bb8114f1396...
I personally think we have the following strenghs:
* Algorithms. Writing SIMD loops is very hard. We give you a lot of ready to go loops. (find, search, remove, set_intersection to name a few). * zip and SOA support out of the box. * High quality codegen. I haven't seen other libraries care about unrolling/aligning data accesses - meanwhile these give you substantial improvements. * Supporting more than transform/reduce. We have really decent compress implemented for sse/avx/neon implemented for example.
The following weaknesses:
* We don't support runtime sized sve/rvv (only fixed size). We tried really hard, but unfortunately just the C++ language refuses to play ball there. Here is a discussion about that https://stackoverflow.com/questions/73210512/arm-sve-wrappin...
If this is something you need we recommend compiling a few dynamic libraries with the correct fixed lengths. Google Highway manage to pull it off but the trade off is a variadics interface that I personally find very difficult.
* Runtime dispatch based on arch.
We again recommend dlls for this. The problem here is ODR. I believe there is a solution based on preprocessor and namespaces I could use but it breaks as soon as modules become a thing. So - in the module world - we don't have an option. I'm happy for suggestions.
* No MSVC support
C++20 and MSVC is still not a thing enough. And each new version breaks something that was already working. Sad times.
* Just tricky to get started.
I don't know what to do about that. I'm happy to just write examples for people. If you wanna try a library - please create an issue/discussion or smth - I'm happy to take some time and try to solve your case.
We talked about the library at CppCon: https://youtu.be/WZGNCPBMInI?si=buFteQB1e1vXRT5M
If you want to learn how SIMD algorithms work, here are a couple of talks I gave: https://youtu.be/PHZRTv3erlA?si=b87DBYMDskvzYcq1 https://youtu.be/vGcH40rkLdA?si=WL2e5gYQ7pSie9bd
