This is interesting. We also trying to use BLAS to accelerate linear algebra
operations in other algorithms such as {{KMeans/ALS}} and I have some basic
performance test result. I would like to contribute to this task after
SPARK-7159 finished. Thanks!

> Multinomial logistic regression uses LogisticAggregator class for gradient
> updates. We should look into refactoring MLOR to use level 2 BLAS operations
> for the updates. Performance testing should be done to show improvements.
