> Blockify distance computation in k-means
> ----------------------------------------
>
> Key: SPARK-8519
> URL: https://issues.apache.org/jira/browse/SPARK-8519
> Project: Spark
> Issue Type: Improvement
> Components: MLlib

> The performance of pairwise distance computation in k-means can benefit from
> BLAS Level 3 matrix-matrix multiplications. It requires we update the
> implementation to use blocks. Even for sparse data, we might be able to see
> some performance gain.
