title2. Account association

There are multiple ways to get an account budget (see also UG2.2 Become a User):

  • A Principal Investigator (PI) of an already existing account can add you to it in the UserDB portal;
  • You can apply for your own project by submitting your proposal for an ISCRA, PRACE projects or HPC Europe Transnational Access Programme;
  • If you are a member of an Italian research Institution with already existing agreements with CINECA (in this case, send an email to superc@cineca.it);
  • General users and Industrial Applications (send a request to superc@cineca.it)

Once your username has been associated with an active account, you can request access to our HPC clusters by clicking on the button "Submit" on your HPC Access page. (The button appears only after you have been associated with an account).


After we have granted you the access, you will receive two emails: one with the username and another with the link to the page where you can configure the two-factor authentication (2FA) needed to access our clusters. You can follow the "How to activate the 2FA and the password to be used to login. Once logged, you will be asked to change your password (you can always change your password later on with "passwd" command). Our policy about password can be found on the "UG2.3 Access to the Systems" configure the OTP" page with dedicated instructions on how to configure the 2FA. You will also have to install a smallstep client ("How to install the smallstep client") on your personal PC to download a temporary certificated needed for the login. During 2FA configuration you will be also asked to set a password. Please you can find our policy about password definition at the dedicated page.

Remember: Login credentials are to be considered strictly personal, meaning that NO SHARING between members of the same working group is expected to happen. Every single user entitled with login credentials is to be considered personally responsible for any misuse that should take place.

title3. Connecting to the cluster

Once you have received your credentialsconfigured the 2FA, you can login to the cluster in which the budget account you are associated with is active.The simplest way is to , by:

  • open a terminal and
type


> ssh <username>@login.<cluster>.cineca.it

(Windows users can find here the instructions)


Alternative ways to connect to CINECA HPC clusters are described on the "UG2.3 Access to the Systems" pageAt present the only method to login to our clusters is via 2FA authentication. Please write to superc@cineca.it if you find problems in configuring and using it.

Available clusters are Galileo100, Marconi, Marconi100  (m100) and Leonardo (UG3.0 System specific guides).

Important: You can login only to clusters where you have active budgets on it.

title4. The "saldo" command

On the cluster, you can keep an eye on your budget of hours using the command:

> saldo -b

This lists all the accounts associated with your username on the current cluster, together with the "budget" and the consumed resources.
Additional info on this very useful command and our billing policy can be found on the "UG2.4 Accounting" page.

One username can use multiple accounts, and one single account can be used by multiple usernames (and even on multiple platforms), all competing for the same budget.
