I apologize in advance if this topic is not of interest to you.

At the GLADE meeting, there were some good discussions on the need for more 
benchmark, particularly regarding timing and speed. For CitcomS, our 2008 G^3 
paper provides quite extensive benchmark calculations for Stokes' flow, 
isochemical and thermochemical convection with large viscosity contrast (up to 
1e7). In Table 1 of this paper, we also include some information on the speed 
and CPU time for a typical calculation, and scaling up to 3000 cores. 

Needless to say, more benchmarks and comparisons with other codes will be 
helpful. If any of you are interested in doing this, I would be more than happy to 
participate or take the lead. I can provide all those solutions published in the 
paper including analytical solutions for Stokes' flow.
