> Introduce a VectorizedBLAS class that implements hardware-accelerated BLAS operations. This feature is hidden behind the "vectorized" profile that you can enable by passing "-Pvectorized" to sbt or maven.
> The Vector API has been introduced in JDK 16. Following a discussion on the mailing list, this API is introduced transparently and needs to be enabled explicitly.
