Job Submission on ARCHER2

Unified Model
1

Hi,

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:

Unloading /usr/local/share/epcc-module/epcc-module-loader

Warning: Unloading the epcc-setup-env module will stop many
modules being available on the system. If you do this by
accident, you can recover the situation with the command:

module load /work/y07/shared/archer2-modules/modulefiles-cse/epcc-setup-env

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,
Ros

Hi,

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 @login.archer2.ac.uk.

Following the advice given for ticket #2865 which produced a similar error, I have checked my known_hosts file. Here I only have the @login-4c.archer2.ac.uk login, not the @login.archer2.ac.uk. 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,.ac.uk option.

Thanks,
Hannah

Hi Hannah,

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

Ros.
