GfsOutputTiming

From Gerris

OutputTiming gives a summary of time consuming of the simulation including the simulation speed measured in how many grids* timesteps can be done per second.

for example

Timing summary: 5 timesteps 20507 node.timestep/s

means it is the 5th timestep, currently 20507 grids*timestep can be done in one second. If your simulation scale is 40 000 grids (static) and 100 timesteps, the estimated simulation time is 40 000grids*100steps/(20507 grid.timestep/s)=195s.
