Yanbo Liang commented on SPARK-17134:
-------------------------------------

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. Thanks!

> Use level 2 BLAS operations in LogisticAggregator

> 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.
