[I] [QDP] improve memory usage [mahout]

["rich7420 (via GitHub)" <gi...@apache.org>]

rich7420 opened a new issue, #667:
URL: https://github.com/apache/mahout/issues/667

   ### Summary
   Presently, we initialize the memory with all zeros and then write the computed results. We could use `unsafe_alloc` instead, which would save about half of the time because `unsafe_alloc` writes only once.
