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?
