Comment (by barry.wardell):

 Replying to [comment:4 barry.wardell]:
 > I have verified that the tests pass on SSE 4.1, SSE 4a and SSE 2
 machines with vectorisation enabled immediately after commit
 4c04a8bc35cf7706e144fe771ba5d6c907f5a455 which was just before the recent
 schedule changes.

 Correction: I have verified this only for SSE4.1 and SSE2. Although I
 tested on Kraken which has CPUs supporting SSE4a, it turns out that the
 Vectors thorn only used SSE2. I guess the SimFactory optionlist for Kraken
 must not enable SSE4a? Is there a machine which does compile using SSE4a?
 Can Kraken be modified to do so?
