Yep a suffix _simd would make perfect sense too.

If people contribute and maintain XSIMD kernels then great.
If people contribute and maintain auto-vectorizable kernels then great.

Bikeshedding moment: we use suffixes today for instructions sets would it
make sense to continue that for consistency.
`scalar_arithmetic_simd.cc`?

Hi,
I started a document where we can crowdsource the 2022-04
board report:
https://github.com/apache/arrow/pull/12759
(We used Goolge Docs before but I want to try pull request
this time.)
If you're a committer, you can push your changes
directly. Others can leave comments/suggestions.

Yep, that's basically what I'm suggesting. If someone contributes an xsimd
kernel that's faster than the autovectorized kernel, then it'll be seamless
to switch.
The xsimd and autovectorized kernels would share the same source file, so
anyone contributing an xsimd kernel would just have to change t

I think the following needs to happen:

There is already a dynamic dispatch facility see: arrow/util/dispatch.h
Since we're rolling our own dynamic dispatch, we'd still have to compile

Following up on today's sync-up:
We're looking to start IP clearance of the JDBC driver in
https://github.com/apache/arrow/pull/12254
I believe we discussed merging the PR into a branch to start the process.
What else is involved in this process?

I think a big part of this is how fragile the current kernel system
implementation is. It seems to rely on templating lots of different parts
of kernels and hoping com

Hi all,
xsimd core developer here writing on behalf of the xsimd core team ;)
I just wanted to add some elements to this thread:
- xsimd is more than a library that wraps simple intrinsics. It provides
vectorized (and accurate) implementations of the traditional mathematical
functions (exp, sin,

I've noticed that we include xsimd as an abstraction over all of the simd
