From outside ECMWF, you may use Teleport through our gateway in Bologna, jump.ecmwf.int. Direct access through ECACCESS service is not available.

$> tsh login --proxy=jump.ecmwf.int
$> ssh -J user@jump.ecmwf.int user@hpc-login
# or for users with no formal access to HPC service:
$> ssh -J user@jump.ecmwf.int user@ecs-login

For all the details of this connection method please see the Teleport documentation, where you will find how to best configure your SSH settings.

You may also connect via SSH from another ECMWF platform such as the Linux VDI.

$> ssh hpc-login
# or for users with no formal access to HPC service:
$> ssh ecs-login

SSH key-based authentication within ECMWF

The first time you log in, we strongly recommend you set up your local SSH key-based authentication with the following command:

$> ssh-key-setup

This step is required for many tools and applications to work well, such as ecinteractive, ecflow, and ecaccess jobs, as well as convenient access from our VDI service.

See also HPC2020: Persistent interactive job with ecinteractive if you wish to customise the resource limits of your interactive session.

Upon logging in, please take a look at the message of the day displayed on the login nodes (or review /etc/motd). 

Password access

If you have not changed your password since 18 January 2021, password access may not work.

List of main entry points

You can use the hpc-* or hpc2020-* names in the table below if you just need to use the default HPCF complex, or the specific names for each of the complexes. For ECS, you may use the ecs-* names. Your usual interface to connect would be the *-login names, and for remote submission of jobs we would recommend using the *-batch names as they are dedicated login nodes for job submissions. If you need to set up a cronjob, then the *-cron names are to be used.

    Hi. Is there any more information on setting up crons anywhere? I ssh'd into hpc-cron but I appeared to end up on the same host that I do with hpc-login. Is there a hidden difference?

    If I set up a crontab in the usual way on this machine, is it persistent?

      Hi Luke, hpc-cron is the correct place where to set up user crons. We will create more detailed documentation soon.
