This would deserve an upvote if the code was legally usable.

Since it's not too easy to spot, the paper refers to http://www.ti.uni-bielefeld.de/html/people/moeller/tsimd_war... and that page has a "Software Download" section with a custom license that has significant arbitrary restrictions:

* "agrees not to transfer [...] to other individuals"

* "agrees not to use the software [...] where property of humans [is] endangered"

* etc.

I.e. this "contribution" would only be relevant if was usable under a really free license, e.g. one of: https://www.gnu.org/licenses/license-list.html#SoftwareLicen...
