The system has four login nodes and we use so-called ''DNS round-robin scheduling'' to load-balance the incoming connections between the nodes. If you open multiple SSH sessions to bwUniCluster 2.0, these sessions will be established to different login nodes, so processes started in one session might not be visible in other sessions. |

Login Hostnames of the bwHPC Clusters
From outside the clusters users can only use the login nodes to submit jobs.
Please go to the section of the cluster you want to login:
bwUniCluster 2.0 Hostnames
The system has four login nodes. The selection of the login node is done automatically. If you are logging in multiple times, different sessions might run on different login nodes.
Login to bwUniClister 2.0:
| Hostname | Node type |
|---|---|
| bwunicluster.scc.kit.edu | login to one of the four login nodes |
| uc2.scc.kit.edu | login to one of the four login nodes |
In general, you should use automatic selection to allow us to balance the load over the four login nodes. If you need to connect to specific login nodes, you can use the following hostnames:
| Hostname | Node type |
|---|---|
| uc2-login1.scc.kit.edu | bwUniCluster 2.0 first login node |
| uc2-login2.scc.kit.edu | bwUniCluster 2.0 second login node |
| uc2-login3.scc.kit.edu | bwUniCluster 2.0 third login node |
| uc2-login4.scc.kit.edu | bwUniCluster 2.0 fourth login node |
BINAC Hostnames
The system has three login nodes. You have to select the login node yourself.
Login to BINAC:
| Hostname | Node type |
|---|---|
| login01.binac.uni-tuebingen.de | BINAC first login node |
| login02.binac.uni-tuebingen.de | BINAC second login node |
| login03.binac.uni-tuebingen.de | BINAC third login node |
JUSTUS2 Hostnames
The system has four login nodes. The selection of the login node is done automatically. If you are logging in multiple times, different sessions might run on different login nodes.
Login to JUSTUS2:
| Hostname | Node type |
|---|---|
| justus2.uni-ulm.de | login to one of the four login nodes |
In general, you should use automatic selection to allow us to balance the load over the four login nodes. If you need to connect to specific login nodes, you can use the following hostnames:
| Hostname | Node type |
|---|---|
| justus2-login01.rz.uni-ulm.de | JUSTUS2 first login node |
| justus2-login02.rz.uni-ulm.de | JUSTUS2 second login node |
| justus2-login03.rz.uni-ulm.de | JUSTUS2 third login node |
| justus2-login04.rz.uni-ulm.de | JUSTUS2 fourth login node |
Helix Hostnames
The system has four login nodes. The selection of the login node is done automatically. If you are logging in multiple times, different sessions might run on different login nodes.
Login to Helix:
| Hostname | Node type |
|---|---|
| helix.bwservices.uni-heidelberg.de | login to one of two login nodes |
In general, you should use automatic selection to allow us to balance the load over the four login nodes.
NEMO Hostnames
The system has two login nodes. You have to select the login node yourself.
Login to NEMO:
| Hostname | Node type |
|---|---|
| login.nemo.uni-freiburg.de | NEMO first login node alias |
| login1.nemo.uni-freiburg.de | NEMO first login node |
| login2.nemo.uni-freiburg.de | NEMO second login node |
