We already discussed this. honestly, i don't see it as a priority for a number of reasons. (1) it increases dependency footprint (2) it only increases speed (i think) of random access vectors (3) it still will not get us anywhere close in terms of matrix-matrix operations to where mkl, openblas and gpu might (see discussion on top of spark dev list about these things and performance behcnhmarks of algebra there. They now include even things like memory-gpu transfer time). On Tue, Mar 10, 2015 at 2:56 PM, Pat Ferrel <[email protected]> wrote: > Anyone looking at this?
