Ludovic Henry created SPARK-33882:
-------------------------------------

             Summary: Add a vectorized BLAS implementation 
                 Key: SPARK-33882
                 URL: https://issues.apache.org/jira/browse/SPARK-33882
             Project: Spark
          Issue Type: New Feature
          Components: ML
    Affects Versions: 3.2.0
            Reporter: Ludovic Henry


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.
