Repository for the Python Crop Simulation Environment

Dependencies

If you git clone https://github.com/feliksik/ggcmi in ~/basedir/, the directory ~/basedir/ggcmi is created. The Docker build file assumes that the following extra files/dirs exist (currently you have to put them there manually).

• basedir/ggcmi/deps/
• basedir/ggcmi/deps/futil.so
• basedir/ggcmi/deps/netcdf-4.3.2.zip
• basedir/ggcmi/deps/netcdf4-python-master.zip
• basedir/data/
• basedir/data/Dump20141114.sql
• basedir/data/OtherInputs/...
• basedir/data/AgMERRA/...
• basedir/data/geodata/...
• basedir/output/

Building

You can run this repository in a docker container as follows:

• install docker; on ubuntu you can do
  • curl -sSL https://get.docker.com/ubuntu/ | sudo sh
• build the docker image
  • docker build -t ggcmi .
  • this will make it visible in the listing of docker images

RUNNING

• edit config.sh to your liking, and run:
  • ./start-worker.sh
  • it will run a worker with the configuration of config.sh
  • if your config.sh specifies ggcmi-mysql as the DB_HOST, this means you wish to run a local Docker-based mysql database. It will be started, if it does not already exist.

Congratulations, you are now running the Global Gridded Crop Model Intercomparison (GGCMI) in a test environment!

If you want to run with multiple worker nodes, you go as follows:

• set up a MySQL database with the worker data on a central server
• on every worker node:
  • install:
    • the docker image
    • the required data directory
    • the config.sh configured to use the remote MySQL host (it is identical on each worker node)
  • ./start-worker.sh
  • relax, and see results coming in
