[Users] cactus performance

Hello,

Is there documentation about performance of Cactus ETK in large machines. I have some questions regarding best performance according to initial conditions, calculation time required, etc. If there are performance plots like Flops vs. Number of nodes would help me as well.

Other main question I have is if Cactus scales in large machines.

I am using McLachlan, but any other application would give me an idea of what I should expect for my runs in big machines.

Thanks, Jose
