Adam Ilardi updated MAHOUT-1429:
--------------------------------
Description: I wrote a simple patch to do the calculation in parallel. It
could be better but it gets the job done. Is there some other (Matrix transpose
dot matrix) code in mahout that is already parallel? I will reuse that if it
exists. (was: I wrote a simple patch to do the calculation in threads. It
could be better but it gets the job done. Is there some other (Matrix transpose
dot matrix) code in mahout that is already parallel? I will reuse that if it
exists. )
