||
| − | |||
| − | Granting access and issuing a user account for '''bwUniCluster 2.0''' requires the registration at the KIT service website [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu] (step B). However, this registration depends on the '''bwUniCluster entitlement''' issued by your university (step A). |
||
| − | <br> |
||
| − | |||
| − | == Step A: bwUniCluster entitlement for registration == |
||
| − | '''The entitlement is called bwUniCluster (not bwUniCluster 2.0)''' and each university issues the bwUniCluster entitlement '''only''' for their own respective members. Some have established on-line processes or provide downloads of the entitlement application forms. If there is no link behind the name of an institution in the following list, please contact the local IT support services: |

||
| − | |||
| − | After completing step A, i.e., after successfull issueing of the bwUniCluster entitlement, you have to register yourself for the service. To do so please visit [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu] and complete the following steps. |
||
| − | |||
| − | 1. Select your home organization from the list on the main page and click '''Proceed''' or '''Fortfahren'''. |

| − | 2. You will be directed to the ''Identity Provider'' of your home organisation. Enter the user ID / username and password of your home organisation - this is usually the same password used for your e-mail account and other services - and click on '''Login''', '''Einloggen''' or something similar. |
||
| − | |||
| − | 3. You will be redirected back to the registration website [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu/]. If you are logging into bwIDM for the first time, there will be a summary screen which shows the account details your home institution is providing to the central system. Please check that all data is valid and then click on '''Continue''' or '''Weiter'''. |
||
| − | |||
| − | 4. Once you have successfully logged into the bwIDM system, you will be greeted by a home screen showing all state-wide services you have access to. There will be a box labelled "bwUniCluster". Click on '''Register''' or '''Registrieren''' to start the registration process. |

||
| − | Your bwUniCluster 2.0 '''password''' is the service password you set during the web registration (compare step 7 of chapter 1.2). At any time, you can set a new bwUniCluster 2.0 password via the registration website [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu] by carrying out the following steps: |
||
| − | # visit [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu] and select your home organization |
||
| − | # authenticate yourself via your home-organizational user id / username and your home-organizational password |
||
| − | # find on the left side '''bwUniCluster''' and select '''Set Service Password''' |
||
| − | # set new service, i.e. bwUniCluster, password, repeat it and click '''Save''' button. |
||
| − | # the page answers e.g. "Das Passwort wurde bei dem Dienst geändert" ("password has been changed") |
||
| − | # proceed to log in using the new password in the next step |

| − | = Establishing network access = |
||
| − | |||
| − | Access to bwUniCluster 2.0 is limited to IP addresses from within the campus networks of the respective home institutions of our current users. If you are outside of one of these networks (e.g. in your home office instead of in your campus office), a VPN connection to your home institution has to be established first (see e.g. [1] for the KIT). |
||
| − | |||
| − | = Login = |
||
| − | |||
| − | After finishing the web registration and making sure that you have access to a network from which you have access to bwUniCluster 2.0 (e.g. by establishing a VPN connection), the HPC cluster is ready for your '''SSH''' based login. Available SSH applications are: |
||
| − | |||
| − | * built-in command under Linux and macOS using the application ''terminal'' |
||
| − | * [http://mobaxterm.mobatek.net/ MobaXterm] under Windows |
||
| − | |||
| − | bwUniCluster 2.0 has four + two dedicated login nodes. The selection of the login node is done automatically and is based on a round-robin scheduling. Logging in another time the session might run |
||
| − | on the other login node. |
||
| − | |||
| − | Only the secure shell ''SSH'' is allowed to login. Other protocols like ''telnet'' or ''rlogin'' |
||
| − | are not allowed for security reasons. |
||
| − | |||
| − | == Login applications: Linux and macOS == |
||
| − | |||
| − | A connection to bwUniCluster 2.0 can be established by the command: |
||
| − | |||
| − | <pre> |
||
| − | $ ssh <UserID>@bwunicluster.scc.kit.edu # or |
||
| − | $ ssh <UserID>@uc2.scc.kit.edu # Login on a Cascade-Lake-node - or |
||
| − | $ ssh <UserID>@uc1e.scc.kit.edu # Login on a Broadwell-node |
||
| − | </pre> |
||
| − | |||
| − | If you are using ''openSSH'' (usually installed on Linux based systems) and you want to use a GUI-based application on bwUniCluster 2.0 you should use the |
||
| − | ''ssh'' command with the option ''-X'' |
||
| − | |||
| − | <pre> |
||
| − | $ ssh -X <UserID>@bwunicluster.scc.kit.edu # or |

| − | == Allowed activities on login nodes == |
||
| − | |||
| − | The login nodes of bwUniCluster 2.0 are the access point to the compute system and to your bwUniCluster 2.0 $HOME directory. The login nodes are shared with all the users of bwUniCluster 2.0. 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 postprocessing of your batch jobs. |
||
| − | |||
| − | To guarantee usability for all the users of bwUniCluster 2.0 <span style="color:red;font-size:100%;">'''you must not run your compute jobs on the login nodes'''</span>. Compute jobs must be submitted to the |
||
| − | [[bwUniCluster Batch Jobs|queueing 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 postprocessing of batch jobs must also be submitted to the [[bwUniCluster Batch Jobs|queueing system]]. |
