You are correct - Tableau never went into great details about what it is and how it works however it is touched on in Alan Eldridge's Designing Efficient Workbooks v9.2:
Secondly, the data engine will now use SIMD instructions to perform low-level operations such as plus, minus, divide, min, max, sum, etc. on multiple data in parallel. This means that basic computations can 29 be performed more quickly. This improvement is only available on CPUs that support SSE 4.1 however most modern Intel and AMD CPUs do.

I too was searching for this term, along with many others that Tableau listed in their Practice Exam Guide and found a page that explains them all. From what I can tell, they are all features that were added into Tableau 9.0 and are related to performance in one way or another.
