Access to the Linux-Cluster
Access to the Linux-Cluster is possible via a SSH connection to the login-node its-cs1.its.uni-kassel.de. You need an account of the university of Kassel (UniAccount) and you have to grant yourself the access rights. To do this, open the IDM UserApp (userapp) and select "Request access"/"Linux-Cluster". The access is possible from the next day.
Your workstation need now a SSH client software (see below). Do not run your programs on the login-node its-cs1.its.uni-kassel.de, instead use the Batch processing with SLURM.
Windows
To access the cluster over the workstation its-cs1.its.uni-kassel.de with your UniAccount you can use the SSH client software MobaXterm (recommended) or PuTTY.
After successful login you be in your home directory. To transfer data you can connect your own computer with your home directory (recommended), too or use the free software WinSCP.
Linux
Linux operating systems have the SSH client already included, so here the command ssh with UniAccount followed by target host is sufficient:
ssh -Y uk00123@its-cs1.its.uni-kassel.de |
You should be in your home directory now. To transfer of your data you can connect your computer with your home directory (recommended), too or use alternative the following commands:
scp :
scp file.txt uk00123@its-cs1.its.uni-kassel.de:/home/users/000/uk00123 |
or sftp:
sftp uk00123@its-cs1.its.uni-kassel.de Connected to its-cs1.its.uni-kassel.de. sftp> |
To save yourself typing the entire host address, you can use the file config in the folder .ssh of your home directory:
cat ~/.ssh/config |
With this configuration you can simply use the shorter command ssh cs1 for login.
Disc Quota
Your available disk quota:
directories (global variables) | quota | availability | backup | inventory time |
|---|---|---|---|---|
homedirectory | 10 GB | global (gpfs, 1 GBit/s pro Node) | yes | unlimited |
| group ressources | variabel | global (gpfs, 1 GBit/s pro Node) | yes | variabel |
/work | 8 TB | global (gpfs, 1 GBit/s pro Node) | no | 30 days |
/local | 1,8 TB | local (RAID 0) | no | 30 days |
| /tmp | 2GB | local | no | 2 days |
- Global available means that the diretory is available on each node of the cluster
- Local available means that the directory is on the local disk of a node and only reachable from this node
- A temporary inventory time means that the data will be deleted when they are older than the guaranteed inventory overtime
- Note that you share the space on /work with other users. If the directory is full, no one can use it anymore. Please take a look on the allocation from its-cs1 before a great copy proess with df -h /work.
- The disk quota of the home directory can be increased. You have to make an request to contact with a description of the reason.
