This thread is complaining about DMDA costing multiple vectors worth of memory.
https://groups.google.com/d/msg/claw-dev/JwIjL5e48No/NOizc6i88gkJ We currently set a lot of stuff up eagerly so that it can be accessed using non-collective accessors. When a Krylov method is used or a matrix is assembled, that stuff is in the noise, but for explicit methods, it can be the limiting factor for problem size. Should we do something about this?
