The ford1 disk contains the libraries, baselibs, and boundary conditions needed to run the model. GMAO support can help you with these two items. If you want to run the full model you will need one of the newer 8 core (with hyperthreading) machines with 8 GB of memory. The single column model can be run on one of the older machines with less cores and memory. | ||

You can setup an experiment now as usual. To do a full model run use the gcm_setup script as usual. Once the experiment is setup and you have your restarts copied run the gcm_run.j script. To run the single column model copy the scm_setup script to the directory you want to run the experiment in. Run the scm_setup script in this directory. Currently on /ford1 are boundary conditions for 144x91 and c48 using the Reynolds ocean. If you have a newer machine with 8 cores (including hyperthreading) you can run 144x91 on a 2x4 layout and c48 on a 1x6 layout. For reference, using c48, on the Reynolds ocean, no gocart, with the standard history had a highwater memory use of 7.3 GB and took about 9 minutes running on a 1x6 layout. | You can setup an experiment now as usual.
