Notes

How to access payu

All ACCESS-NRI models and critical supporting software such as payu is located in /g/data/vk83 on NCI. It is necessary to be a member of the vk83 project to use ACCESS-NRI supported versions of payu. See NCI Documentation for more information about how to join a project

To access payu version 1.1.3:

module use /g/data/vk83/modules
module load payu/1.1.3

payu is installed on gadi using an automated deployment process. This ensures a consistent software environment and the design allows for multiple versions of payu to be maintained, so if there are changes which are incompatible with your experiment you can use an older compatible payu version.

This new version has been deployed to vk83 and is now the default version. It contains a number of bug fixes and improvements and is the recommended version to use. The previously deployed version (1.1) is deprecated and will be removed when the next version of payu is deployed, or within 3 months, whichever is sooner.
