Run ECCO Solutions From Julia

Run ECCO Solutions From Julia#

The MITgcm.jl package let’s you run ECCO4 solutions from scracth in two simple commands – MITgcm_config and run.

See the MITgcm.jl docs here for more detail and examples like this.

In the Code Below:#

  • MITgcm_config defined the model configuration.

  • we reset parameters, assuming that inputs have already been downloaded and the model compiled

    • if that’s not the case, just comment out the push!(MC.inputs... lines, and run will download data and/or compile the model.

  • run(MC) creates a run folder, sets everything up in that folder, and creates a submission script.

  • run(qsub $(script)) submits the job to the queuing system from within julia.

using MITgcm

run_folder=tempname()
params=read_toml(:ECCO4)
MC=MITgcm_config(inputs=params,folder=run_folder)
