Moltres init: In-depth scaling tests about publications HOT 8 CLOSED

I can do strong and weak scaling study for moltres on BW, learning it right now in my Parallel Algos class.
If interested, pick your favorite case which is appropriate for the study.

It depends on how deep we want to study that. You have mentioned 608 cores in an introduction, but I think 320 cores (10 nodes) quite enough.
So, pick a problem which requires ~2-10 minutes on 320 cores.

For weak scaling we have to fix a number of points per processor, so, I will scale mesh while changing core number, hope I know how to do it in gmsh.

@katyhuff Don't you mind if I'd take this assignment?

@andrewryh Sounds good to me, but it's up to alex. I think he thought this topic was interesting and self-assigned it .

@andrewryh I think I would run moltres/problems/publication_level_cases/3d_steady_state/3d_auto_diff_rho.i and change end_time to something like 1 second. You might have to make it even smaller to get a simulation time in the minute to ten minutes range.

Gotcha.
I'll change somehow mesh to variate number of grid point per processor also.
Thank, don't forget assign it to me :)
