Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Significantly faster quicksort using SIMD
Interesting post and paper, thanks!
Sometimes the state of the art is not found in another paper but somewhere else, e.g,. there is vxsort by Dan Shechter (damageboy):
https://github.com/damageboy/vxsort-cpp/tree/master
He uses a similar approach and while I'm not sure how it compares to the Blacher et al version, I expect it to be in the ballpark.

Sorting with SIMD
The original (AFAICT) work on SIMD quick sort, also mentioned in the google post also implemented pointer sort by loading a pointed key using gather instructions and the method can be used for an array of structs. https://github.com/vkrasnov/avx_qsort/blob/master/qsort_AVX2...

Significantly faster quicksort using SIMD
I'm the co-author of one of the papers referenced in the blogpost, (Fast Quicksort Implementation Using AVX Instructions), we did write the AVX512 code back in 2015, just had nowhere to run it, at least publicly. The paper also very explicitly says that the lookup tables can be instead replaced by the AVX512 compress instructions. The code for that paper is available in https://github.com/vkrasnov/avx_qsort
