Payu is a workflow manangement 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 mom
payu build
payu run

Currently, payu is very highly customised for users of NCI computing environments in the v45 user group, with a very strong dependence on environment modules, the PBS scheduler, and an MPI runtime environment. Using payu on other machines will require either the installation of these services or a significant modification of the codebase.
