This article describes how to log into the KISSKI cluster. It contains 💎 sections which are optional and help you if you are stuck at a particular step.
Getting started
If you would like to run code on the KISSKI cluster, you need an account for the cluster.
Create an account You will need an account at https://academiccloud.de/ to apply for compute ressources and to log into the cluster. If you are working at a research institute or university, you might already have an account. In this case, skip this step. If you do not yet have an Academic ID, please register on the page mentioned.
Apply for compute ressources You can apply for compute ressources here. Please click there on the “Book” button.
1. Logging in
To log into the cluster, complete the following steps.
- Upload an ssh key
Create an ssh key on your computer (Github). For security reasons, it is important that you specify a password when creating this key. The generated key consists of a private part and a
.pubpart. You will need the.pubpart in the next step.Go to https://id.academiccloud.de/ and upload your key as a public ssh public key (-> Security -> SSH Public Keys). It will take some time (~10 minutes) until this key is synchronized in the whole system.
- Test access Now you can test whether you have access to the system. GWDG need to add you to the system, so this step only works when they have already done so. You will receive an e-mail with your user name once you have been added to the project.
Open a shell and adapt the following command:
ssh -i .ssh/your-key your-username@glogin9.hlrn.de
- replace
your-usernamewith the username you have gotten via mail - replace
.ssh/your-keywith the file path to your newly created ssh key
You are now on the frontend.
💎 If your key “Identity file” is not found, double-check that the path you have provided exists and contains your generated key
2. Running Code
Next steps would be to run code with Slurm. For an introduction to this, please have a look at this course. To find out more about GPU usage, please have a look here.
