Which parameters determine the spin up time

Hello,
I want to simulate the GPP and NPP changes from 1970-2014, so I created a case and want to complete the AD_spin up process for 600 years using 1965-1969 atmospheric forcing data. But in the result file the last result file is test45.clm2.h0.0121-01-01-00000.nc, did I complete the 600 year acceleration process? I set STOP_N=120, do I need to set STOP_N=600 to complete the 600 year spin up process? I want to complete the process directly and without setting the RESUBMIT parameter


./create_newcase --case test45 --res f09_g16 --compset 1850_DATM%GSWP3v1_CLM50%BGC_SICE_SOCN_SROF_SGLC_SWAV --compiler intel --mach myintel --run-unsupported
cd test45
./xmlchange CLM_ACCELERATED_SPINUP = on
./xmlchange CLM_FORCE_COLDSTART = on
./xmlchange DATM_CLMNCEP_YR_START = 1965
./xmlchange DATM_CLMNCEP_YR_END =1969
./xmlchange STOP_N = 120
./xmlchange STOP_OPTION = nyears
./case.setup
./case.build

Yes, you need to set STOP_N=600, if you aren't going to use the RESUBMIT capability.
