ECP 10: Memory reduction techniques for higher-order

[spdomin]

Activities:

1. Establish static condensation approaches with local, fast solves.
2. Deploy preconditioner coarsening strategies which may require only the P=1 system to be stored.
3. Evaluate matrix-free methods for both advection/diffusion and possible PPE.

Is there some some pointers for reading one can start with ? What is the local, fast solve here, LU on small blocks ?

[spdomin]

@srajama1 take a look at the attached reference for the basics of the higher order method:

Also, please interface with @rcknaus as he has some good papers on static condensation and local solves.
