Hi everyone,
I’m currently running a CTSM case with a regional grid of 687*315, using regional surfdata and landuse.timeseries file. I found that during the accelerated spin-up for the I2000 case, it took about 1 minute per model day with 416 processes.
However, after finishing spin-up and switching to the hybrid run for the ihist case (initialized from spin-up restart files), with a 16 GB landuse.timeseries dataset spanning 1980–2023, the model now only runs one model day in about 5 minutes.
Is this large difference in performance normal? Any advice or guidance would be greatly appreciated.
Thanks!
