Thanks ! Yes that's what I was looking for, I didn't dig enough in the manual,
as usual.
Instead of using the emit pragma you may want to look into the [CodegenDecl
Pragma](https://nim-lang.org/docs/manual.html#implementation-specific-pragmas-codegendecl-pragma).
Hello,
That is pretty cool and I am interested also in that. I have taken a look and I
have some remarks.
If I understood correctly your approach, the marked code is selected at runtime
according to the CPU properties. To be able to run on different architectures,
the general code must be comp
AVX2 cpu, forgot that I7 doesn't really narrow it down anymore! The code is
ported from a friends C++ library, which should be good but I could definitely
have introduced mistakes with some of the obscure C bindings.
Awesome ! What generation is your CPU? Haswell or later (AVX2)?
runtime detection is now in, tested only on my i7 in linux so far.
Ok I've fixed the .gitignore / bin directory setup

No not quite. You will write explicit SIMD instructions, but it will
automatically transform them to use the best possible option given runtime
detection. So you can write a loop
I don't know much about SIMD, it looks like your approach is to figure out how
to take nim code and SIMDify it? Sounds like a hard problem. What are your
thoughts about the typed approach? Something like

Yes runtime detection is the plan, the prompt is just a placeholder, so that I
know the decision is happening at runtime.
Thanks on the.gitignore, its ignoring exe but i am in linux!
I'll follow your development and provide input. The library may prove quite
useful for some handcrafted computations in Arraymancer.
My first remark would be to use a ./bin or ./out folder and .gitignore it, you
actually added the produced library to your git repo.
Second, I think instead of as
Details are in the readme. If anyone is interested in this and would like to
provide input or help out please let me know.
