I am 100% new to Julia but wanted to try out LoopVectorization. I installed Julia 1.3.1 and did .Pkg.add(“LoopVectorization”). It failed with:

My CPU is an AMD 8350 and I am running Ubuntu 16.04.

What should I do?

You should probably open an issue in [VectorizationBase](https://github.com/chriselrod/VectorizationBase.jl) to add support for AMD FX processors. If you feel comfortable enough and know a bit about the number of cores and cache sizes of the FX series, you could also try adding it as another special case in [this script](https://github.com/chriselrod/VectorizationBase.jl/blob/master/deps/build.jl#L10) yourself and make a PR, I’m sure this would be greatly appreciated.

Oh I just opened one here: [https://github.com/chriselrod/LoopVectorization.jl/issues/20](https://github.com/chriselrod/LoopVectorization.jl/issues/20) . Is that the wrong place?

The change will have to be made in VectorizationBase, but as they’re both maintained by @Elrod, he could just transfer it, so I’m sure that’s fine too.

Thanks very much!

I had a very old build script that didn’t reflect the fact that [CpuId.jl](https://github.com/m-j-w/CpuId.jl) has been supporting AMD since [July 2018](https://github.com/m-j-w/CpuId.jl/commit/2ac67b055a46d4c3576506351b824cbd850956ed). I have updated and released VectorizationBase v0.1.8.
