Hi Eduardo,
Thanks for chiming in. Just one precision:

In my experience there is no single SIMD library that wraps all possible set of
vector instructions across the most common architectures and at the same time
provides support for all popular compilers while supporting C and C++11/14. (I
mention C because there is an issue for Arrow support in C,
For the record, a PR is now up for bundling xsimd with Arrow C++:

Anyway, those are my thoughts for now.

I would say it's a soft consensus for now, and I would welcome more
viewpoints on the matter.

That is unfortunate, like I said if the consensus is xsimd, let's move
forward with that.

There is an std::simd being envisioned.

The problem is that we need an implementation that's C++11- or
C++14-compliant, that works on major compilers, and that provides
accelerations for common instruction sets. It doesn't seem to be the
I'm open to x-simd if others think it is the best option. I think the last
time this came up I expressed this opinion, but if possible it would be
nice to use something that is on its way to become a standard to avoid
abandonment issues but I don't know enough about the space to understand if
this
Thanks for comments on the SIMD related PR:
https://github.com/apache/arrow/pull/9424.
Agree to adopt the *xsimd *as the SIMD wrapper library for Arrow to avoid a
large maintenance burden. It makes sense.
It seems *ximd *is designed for mathematics calculating and it lacks the
functions like bit/b
