1.) How do I get an account on the Arctur HPC?
Last Updated 4 years ago

After you sign an agreement, you will have to provide us with your ssh public key. We use rsa 2k+ or ed22519 keys.

You can provide us with multiple ssh key for one or more users. All users from your organisations will be attributed to the same organization (this way you can use and share the data between you and see the usage and job status).

LINUX users:

If you don't already have your ssh keypair, create it using for example:
ssh-keygen -t rsa -b 2048


WINDOWS users:

You will need a dedicated application like puttygen to generate the keypair.

Follow this procedure to generate the keypair:
  1. Download the puttygen application to your computer (official link provided above);
  2. Select the settings as shown in the screenshot below;

  3. Click on "Generate" button and move your mouse cursor in the grey area randomly until the green status bar is full and the generated key is revealed

  4. Click on the "Save public key" button and save the new file in a location of your choosing.
  5. Click on the "Save private key" button and save the new file in a secure location of your choosing.

ONCE DONE:
Take great care of your private key, as this is your half of key to access our system. If you lose it, this whole procedure must be repeated.

You will have to send the PUBLIC part of your key to the Arctur team to hpc@arctur.si. They will prepare the access to the HPC system. While you will need the private key to be loaded on your system.

Once your account has been established and confirmed by the Arctur team you can procede and access the system following this instructons.
