Payu

Current release: 1.0.19

Payu is a workflow management tool for running numerical models in supercomputing environments.

Payu was designed to allow users to start running climate models immediately, without having to re-learn the nuances of countless runscripts across countless models. Running a model like the MOM ocean model should only require a few commands:

mkdir new_expt; cd new_expt
payu init -m mom
payu run

Currently, payu is very highly customised for users of NCI computing environments, with a very strong dependence on environment modules, the PBS scheduler, and an MPI runtime environment. Using payu on other machines will require, at a minimum, the installation of these services, as well as a potentially significant modification of the codebase.
