Thomas Jungblut commented on HAMA-221:
--------------------------------------

Hmm you probably need Java7 for that. But I guess you could remove my vector class with that
of mahout-math. I have quite the same interface. 

And I think it is not very scalable. So a DNS would be better. 
Heres a paper about how it could look like:

> Using the BSP model, we could improve the performance of mat-mat multiplication. Let's
evaluation it out on this issue.
