In order to ensure a proper functioning of the ECaccess jobs submissions, including the TC-1 service, it is essential to configure properly the SSH Keys under the user HOME on the Atos systems. See HPC2020: How to connect for more details.
You only need to do this once, and you can do it running the following commandYou could use the following commands to issue a new keys pair and configure them:

$> ssh-keygen -q -t ed25519 -N '' -C "$USER@ecmwf.int" -f /home/$USER/.ssh/id_ed25519
$> cat /home/$USER/.ssh/id_ed25519.pub >> /home/$USER/.ssh/authorized_keys |

Without the SSH keys correctly installed, an ECaccess (TC1) job submission will issue an error message like:

Mail notifications currently not working.
SLURM email notifications (directive "#SBATCH --mail-type=") in ECaccess batch jobs on Atos, including TC-1 jobs, are not working at this moment.
TC-1 jobs by TC-2 users
TC-2 users (z<MS> UIDs) cannot currently submit TC-1 jobs on the Atos systems. While we resolve this issue, we invite those users to use their personal UID to launch a TC-1 job, e.g. to trigger the TC-2 ecflow suite.
