I have done a quick browse of the source code. The following list are the
locations that seems to relate with vectorization.

- Project in exec/vector folder uses hppc. But hppc does not claim the use
of
  SIMD.
- Code in exec/java-exec/src/main/java/org/apache/drill/exec/vector.

But I am sure whether these locations are really related with vectorization.
Can anyone give a hint on this question?
