It is a measure of speed of processing. The number of seconds it takes on average to calculate a timestep.

There is a timestep each 1/2 hour of model time. 15 years (of 360 days) and 1 day in a phase. Totals 259248 timesteps per phase and 3 phases in a model.

It's the average time your system takes to process one timestep for your experiment, Nik.

Each experiment has 3 phases (each of 259248 30 minute timesteps) and trickles results back to the the server every 10802 timesteps (with an larger trickle at the end of each phase to generate temperature and precipitation graphs).

One thing to note is that each month has been standardised to 30 days to simplify the date calculations. It also makes it easier to track the checkpointing, which happens every 144 timesteps (at midnight on 1, 4, 7 etc of each month). When you closing the experiment down it's best to do it just after a checkpoint as that'll ensure you minimise the nimber of recalculations you need to do when you start up again.

I see, very good. Thank you. I saw that in the FAQ, but didn't make the connection.

Thanks again,
