Login to the Clusters
 |
Access to the clusters (bwUniCluster/bwForCluster) is restricted to IP addresses of universities/colleges from Baden-Württemberg (BelWü network). If you are outside the BelWü network (e.g. at home), you must first establish a VPN connection to your home university or a connection to an SSH jump host at your home university. |
SSH Clients
After completing the web registration and setting a service password the HPC cluster is ready for your SSH based login.
Cluster Specific Information
Every cluster has its own documentation for login.
- If you want to login to the bwUniCluster, please refer to
→ bwUniCluster 2.0 - If you want to login to one of the bwForClusters, please refer to
→ BINAC
→ JUSTUS 2
→ Helix
→ NEMO
Allowed Activities on Login Nodes
|
|
To guarantee usability for all the users of clusters you must not run your compute jobs on the login nodes. Compute jobs must be submitted to the queuing system. Any compute job running on the login nodes will be terminated without any notice. Any long-running compilation or any long-running pre- or post-processing of batch jobs must also be submitted to the queuing system. |
The login nodes of the bwHPC clusters are the access point to the compute system, your $HOME directory and your workspaces.
These nodes are shared with all the users therefore, your activities on the login nodes are limited to primarily set up your batch jobs.
Your activities may also be:
- short compilation of your program code and
- short pre- and post-processing of your batch jobs.
Additional Login Information
Following sub-pages go into deeper detail about the following topics:
- How do I find out my cluster username?
- What are the hostnames of the login nodes of a cluster?
- Configuring your shell: .bashrc Do's and Don'ts
These pages are also referenced in the cluster-specific login documentations.
