ESM1.5 Cannot find UM executable

Hello,
Sorry, but I am having the same issue as David.
First time trying to run the model, so I simply followed the steps in
Run ACCESS-ESM - ACCESS-Hive Docs

I tried

module purge
payu sweep
payu run

and

payu sweep && payu-run

but I always get the same error:

Traceback (most recent call last):

I don’t have any conda loaded
Thanks for your help!

Hi @LaurieM.

I’ve moved your query to it’s own topic so the triage team can pick it up.

Today is a public holiday in the ACT, so there probably won’t be anyone who can look at it until then, but off the top of my head I can see you’re trying to access your own executable at /scratch/y99/lcm561/access-esm/bin/um_hg3.exe.

I’d suggest running

payu setup
payu sweep
payu run

and see if that helps payu to guess the right storage flags for your experiment.

Thanks Aidan, but I am not trying to access my own executable. Just trying the default setup as suggested on the Hive: Run ACCESS-ESM - ACCESS-Hive Docs
I have already run the 3 commands you mention.

Hi @LaurieM,
This error looks like you are lacking access to the modules that contain the UM executable. Are you a member of ki32 and ki32_mosrs projects on NCI? If not, send a request to join those groups. Note that this requires having a MOSRS account, which is a separate process.
There was also a temporary workaround in place for some new users, but I don’t know if this is available.
Regards,
David

I believe this is the fallback behaviour when payu can’t find um_hg3.exe in the module that it is supposed to.

Yes you’re correct @dkhutch. I made an incorrect assumption.

Sorry you’ve been inconvenienced @LaurieM. The documentation does cover the requirement for a MOSRS account and project memberships, but if you think that is insufficient we could try and make it more prominent.

ACCESS-NRI is in the process of finalising a Research Partnership agreement with the UKMO. Until that is finalised we have to use the existing processes to grant access to UKMO licensed material, and ACCESS-ESM1.5 uses the UM, which is a UKMO licensed product.

@LaurieM confirmed the problem was not having the correct project memberships. This has been rectified so I will close this topic.
