> > new PRs such as [GH-48765](https://github.com/apache/arrow/pull/48765) backport some performance improvements that were merged in xsimd. > > Is [GH-48765](https://github.com/apache/arrow/pull/48765) correct PR? It seems that it just requires xsimd 14.0.0 and doesn't backport anything. Sorry, wrong PR, I meant GH-47994 > > On top of this, [GH-45331](https://github.com/apache/arrow/issues/45331) may require us to add some CPU detection feature to xsimd, which won't be much use if we cannot use them. > > Does xsimd 14.0.0 already have enough features for [GH-45331](https://github.com/apache/arrow/issues/45331)? Or xsimd 15.0.0? or something will add features for [GH-45331](https://github.com/apache/arrow/issues/45331)? Partially, it has the SIMD micro architecture detection but other features such as BMI2, cache lines... should be added too. It is being tracked in https://github.com/xtensor-stack/xsimd/issues/1245 (current status is that is was only discussed offline). -- This is an automated message from the Apache Git Service.
