Model Name
ACCESS 1.0 Coupled Model as used in CMIP5. Includes UM 7.3 atmosphere, MOSES land surface, CICE sea ice, MOM 4 ocean coupled using Oasis3
The model is not available in the UMUI, instead it is run from a set of shell scripts.
A guide to setting up and running the model on the old supercomputer Raijin can be found at https://accessdev.nci.org.au/trac/wiki/access/ACCESS1.0_raijin
Running on Gadi
NOTE: Consider using ACCESS-ESM 1.5 for new runs on Gadi, it is much simpler to use
1. Build the models
2. Change the executable paths in your *.init file to point to the newly built model executables
cp -f $ACCESS_BINDIR/oasis3_MPI1.20200130.RJ $cpl_exe
cp -f $ACCESS_BINDIR/mom4_MPI1.exe.20200130.VAYU $ocn_exe
cp -f $ACCESS_BINDIR/cice_MPI1.VAYU_6p_20200130 $ice_exe
cp -f $ACCESS_BINDIR/um_hg2-r1.1.exe-20200131 $atm_exe
3. Set the recommended PBS headers for Gadi
#PBS -q normal
#PBS -l ncpus=96
#PBS -l mem=192gb
#PBS -l walltime=00:10:00
#PBS -l wd
#PBS -W umask=0022
#PBS -l storage=scratch/access+gdata/access
4. Set the recommended Decomposition (for a total of 96 cpus, 384 gb memory)
