This page documents the steps to run GFDL idealized AGCM on Odyssey. This include three different configurations (1) a dry core, (2) a moist AGCM with grey-radiation and (3) a moist AGCM with realistic (i.e. RRTMG) radiation. 

  1. For the dry core, first copy a test case folder into your own path from here: 


Among the three subfolders, the input folder contains namelists, input data files; the run folder contains the run scripts as well as post-processing scripts; the srcmods contains any possible source code modifications. 

     2.  For the moist model with grey radiation, please copy a test case folder into your own path from here: 


Again, the three subfolder input, run, srcmods serve the same purpose as this for the dry core above. For this grey radiation model, you can set the ocean condition as a slab ocean or a fixed SST configuration. Please see the *.nml files in the input folder.


For the dry core, on Harvard cluster, often writing to disk is the rate-limiting step. You can use -N 1 to ask slurm to put all your tasks on one node, and utilize the super fast, node-local disk /scratch. See example runscript: ~pchan/script/jetshift/fms-runscript.sbatch.

One can run an ensemble, by applying slightly different initial conditions using src/atmos_spectral/init/spectral_initialize_fields.f90. See example script: ~pchan/script/jetshift/
