    34 **The following might not be necessary**
    35 
    36 Once you have the account, you can setup a public key authentification in order to avoid having to input your password for each run.
    37 You need to have a SSH public/private key pair. If you do not, you can create a SSH public/private key pair by typing the following command and following the prompts (no passphrase necessary):
    38 {{{
    39 #!sh
    40 $your_localhost% ssh-keygen -t rsa
    41 Generating public/private rsa key pair.
    42 Enter file in which to save the key (/Users/username/.ssh/id_rsa):RETURN
    43 Enter passphrase (empty for no passphrase):RETURN
    44 Enter same passphrase again:RETURN
    45 Your identification has been saved in /Users/username/.ssh/id_rsa.
    46 Your public key has been saved in /Users/username/.ssh/id_rsa.pub.
    47 }}}
    48 
    49 Two files were created: your private key `/Users/username/.ssh/id_rsa`, and the public key `/Users/username/.ssh/id_rsa.pub`. The private key is read-only and only for you, it is used to decrypt all correspondence encrypted with the public key. The contents of the public key need to be copied to `~/.ssh/authorized_keys` on your Discovery account:
    50 
    51 {{{
    52 #!sh
    53 $your_localhost%scp ~/.ssh/id_rsa.pub username@your_remotehost:~
    54 }}}
    55 
    56 Now on Discovery, copy the content of id_rsa.pub:
    57 
    58 {{{
    59 #!sh
    60 $your_remotehost%cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
    61 $your_remotehost%rm ~/id_rsa.pub
    62 }}}

    90  - PETSc 3.17 (use the discovery script)
     57 - PETSc 3.19 (use the discovery script)
