ECP 6: Establish and improve strong scaling of linear solves on high aspect ratio meshes #60

Open spdomin opened 8 years ago

spdomin commented 8 years ago

Activities:

  1. Evaluate current solver technologies for high aspect ratio meshes.
  2. Develop improved coarsening and preconditioning techniques.
  3. Evaluate possible algorithmic discretization approach improvements.
  4. Explore approximate LHS contribution’s effect on linear and nonlinear solver convergence.

@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.

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