Access to the Supek cluster
Access to the Supek cluster is possible exclusively through the SSH protocol with the use of keys.
Making keys
| Note |
|---|
When generating keys, choose a good passphrase to protect the private key. You NEVER deliver the private key to other persons or institutions. It is recommended to keep the private key exclusively on your own computer. In case of compromise, notify us immediately. |
Linux
Generate SSH keys from the command line using the command:
...
Load the file ~/.ssh/id_rsa.pub using the web application at www.computing.srce.hr, public keys menu.
MS Windows
Install the PuTTYgen application. After starting the application, press the Generate button, enter the Key passphrase and save the public and private keys. Public key for pasting into OpenSSH authorized_keys file, visible in the picture below, must be uploaded using the web application at computing.srce.hr, public keys menu.
Connecting to Supek
The domains of the access nodes of the Supek cluster are login-cpu.hpc.srce.hr and login-gpu.hpc.srce.hr. The prerequisite for connecting to the cluster is creating SSH keys (the previous step) and uploading the keys via the web application computing.srce.hr. After uploading the key via the web application, you need to wait for a notification that will contain the user name and confirmation of the placement of the public key on the cluster.
Linux
The prerequisite for connection is that the private key that you generated in the previous step is installed on the computer. The connection is made using the command (the username in the example is user):
...
| Code Block |
|---|
ssh -i ~/.ssh/id_rsa user@login-cpu.hpc.srce.hr |
MS Windows
To connect, the Putty tool is used and the path of the private key is entered.
Copying files
| Warning |
|---|
You run the scp command from your local computer in both cases! |
...
| Code Block |
|---|
scp <user>@login-cpu.hpc.srce.hr:<remote-path> <local-path>/<file> |
MS Windows
The WinSCP application is used to copy files between the local computer and the Supek cluster.
