ECP 6: Establish and improve strong scaling of linear solves on high aspect ratio meshes about nalu

[spdomin]

Previous comments captured under spdomin/Nalu:

@spdomin I'd like to start by identifying a set of canonical tests with high aspect ratios and benchmarking their performance. Ideally, the tests wouldn't be too large, so that some analysis might be possible.

@jhux2 Sounds great. The heatedWaterChannel is one that you used before. I can find more next week.

@jhux2 I added a new test for you under /home/spdomin/channelFlow.tar

This is a simple LES channel flow with high AR (around 50). The standard milestone.xml usage results in around 65 iterations. Dropping sensitivities helps. Hope this helps. The case can be run on 8 core without any issue (around a million elements). I think that will be a good case, however, let me know if you need something smaller (harder to find a good case though)..
