Folks, I am wondering how mllib interacts with jblas and lapack. Does it make copies of data from my RDD format to jblas's format? Does jblas copy it again before passing to lapack native code?
I also saw some comparisons with VW and it seems mllib is slower on a single node but scales better and outperforms VW on 16 nodes. Any idea why? Are improvements in the pipeline? Mohit.
