Getting access

Get a username

To access Orfeo, you have to generate a pair of keys (public and private). To obtain the keys, open a terminal (Command Prompt in Windows) and use the ssh-keygen command:

ssh-keygen -t rsa -b 4096 -C 'your_email@example.com'

This command will generate a pair of RSA keys, asking you where to save them. The private key will not have any extension, and the default name should be id_rsa. The public key should have the same name with a .pub suffix. E.G.: id_rsa.pub.

Warning

Be sure to take note of the path for both the public (*.pub) and private keys.

Danger

Keep the id_rsa file safe and do not send it to anyone: it's your private key and should not be known by anyone except you.

Once you have obtained the keys, send an email to support@areasciencepark.it with the subject [ORFEO] user creation name surname copying the contents of your public key (id_rsa.pub) in the email body, also add information about your supervisor or student status needed to handle the request correctly. The email opens a ticket in our ticketing system, and you will be notified by email when your user is ready. Remember to test your connection to Orfeo and report the result by answering the confirmation mail to close the ticket.

Login

To log in via SSH, you can follow these steps:

1. Open a terminal or command prompt on your local machine.
2. Type the following command: ssh username@195.14.102.215. Replace "username" with your username on the cluster we gave you via mail. There is no need to insert any password; a key-based authentication method is in place.

Account & associations

In SLURM, an account is a way to group and manage resources based on project or organizational boundaries. Users typically submit jobs under a specific account, and the associated resource usage is tracked accordingly. We provides an account for each laboratory or company that uses our resources. An association is a mechanism to associate or link resources (usually partitions) with a specific project or group.

Associations together with accounts can be used to define resource limits, priorities, and other policies for a particular group or project.

Tip

To discover your associations and the account you are allowed to use to issue jobs use this command sacctmgr list associations Users=$(whoami) format=Account,User,Partition
