Highway – Efficient and performance-portable SIMD

Re: Highway – Efficient and performance-portable SIMD
#2I'm sorry, it's been a long time some code made me feel so dumb. I mean I thought I had a good grasp on c++ and vectorized code and I can't find a simple example on how to use it properly. The benchmark example made me feel even more dumb.
Can someone help pointing what this code is supposed to do (yes I read the landing page and it doesn't help me much...), are there alternative libraries that do similar things and are there 'simpler' examples somewhere?

No offense, but while it was a bit long, all your questions had answers in the README.md. So if you read it, you speed read it too much.

#4Thanks for posting :) Author here, happy to discuss.

:) The benchmark does contain some boilerplate and extra code for measurements but a simple example is at https://github.com/google/highway/blob/master/hwy/examples/b....
Or how about https://github.com/google/highway/blob/master/hwy/examples/s... for computing floor(log2(i))?

You're right. I went again and it started clicking when I saw references to other SIMD libraries. Thanks and sorry.

Right it gives a taste, indeed.
