OpenFOAM 2.1.1 GGI / AMI Parallel Efficiency Test, Part II

These figures are pretty self-explanatory. Again, these are on single computers. My i7-2600 only has four cores, and the other data set represents a computer with 8 cores (2 x Opteron 2378). It is clear there is a significant parallelizability bottleneck (serial component) in the AMI. However, it seems this bottleneck may be controllable by minimizing AMI interface path face count, if the interface patch interpolation is a serial component.
