[MITgcm-support] Is there any method that we know how much it takes running a model?

[Martin Losch]

Saeid,

I am moving this to a new thread, because it doesn’t have anything to do with netcdf.

Do you mean “before you start the model”? Generally no, but after the model run, you get a list of timings from different sections of the model (note that these are “inclusive”, i.e. when forward_step calls do_the_ocean_phys, then the timing for forward_step includes the time spent in do_the_ocean_phys, etc.).
You could use this information of a short run, to scale it up for a longer run (because you can exclude the length initialization procedures, but just using the time spent in forward_step, that’s how I do it).
Anything else can be just rough estimates based on previous simulations.
