Thanks @RachelLaw. I’ve corrected my original post to remove the accidental space.
Regarding the second part of your question about changing the exe/restarts, my initial guess without more information is that the storage mount points for the exe/restart locations are not being set in the Payu job. Payu tries hard to set these automatically for you but, depending on how you’re doing things, they may not be being set. Could you try explicitly telling Payu to set the storage mount points? In the config.yaml add
storage:
gdata:
- <project-containing-exe-or-restart>
scratch:
- <project-containing-exe-or-restart>
