Job Submission on ARCHER2


I am trying to run my first job on ARCHER2 and have copied the u-cc519 suite from the NCAS um-training guide, however the fcm_make2 is failing. I have followed the instructions to change username, account, reservation and queue but no other changes have been made.

This is the fcm_make2 job stderr:

modules being available on the system. If you do this by
accident, you can recover the situation with the command:

Hi Hannah,

We are currently working on all the practical exercises/suites to iron out any issues ahead of a training course in a couple of weeks’ time so they are in a slight state of flux. The error you detail above has been fixed since you checked the suite out.

Best Regards,

Hi Ros,

Thank you!



Just another question regarding job submission on ARCHER2: I am now trying to run a copy of u-be303/archer2 (UKESM AMIP) and am receiving a RosePOpen error of ‘return-code=255, stderr= Host key verification failed’ with the key mentioned being

Here I only have the login, not the Within the rose editor I am only able to select Archer2 as a host site and can no longer find the option as in the copy of u-cc519 suite to change HPC_HOST to the login-4c.archer2, option.


Hi Hannah,

If you use grep -r * in the rose suite directory you will find it in the site/archer2.rc file.
