= Registration = |
|||
Granting access and issuing a user account for '''''bwUniCluster''''' 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 == |
|||
Each university issues the bwUniCluster entitlement '''only''' for their own members. Details on the issuing process and/or the entitlement application forms are listed hereafter: |
|||
* [[Media:unknown.pdf|Albert Ludwig University of Freiburg]] |
|||
* [[Media:unknown.pdf|Eberhard Karls University of Tübingen]] |
|||
* [http://www.scc.kit.edu/downloads/sdo/Antrag_Benutzernummer_bwUniCluster.pdf KIT] |
|||
* [[Media:unknown.pdf|Ruprecht-Karls-Universität Heidelberg]] |
|||
* [[BWUniCluster_User_Access_Members_Uni_Ulm|Ulm University]] |
|||
* [[Media:unknown.pdf|University of Hohenheim]] |
|||
* [[BWUniCluster_User_Access_Members_Uni_Konstanz|University of Konstanz]] |
|||
* [[Media:unknown.pdf|University of Mannheim]] |
|||
* [[Media:unknown.pdf|University of Stuttgart]] |
|||
<br> |
|||
== Step B: Web Registration == |
|||
After step A and its approval please visit: |
|||
* [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu] |
|||
*# Select your home organization from the list and click '''Proceed''' |
|||
*# You will be directed to the ''Identity Provider'' of your home organisation |
|||
*# Enter your home-organisational user id / username and your home-organisational password and click '''Login''' button |
|||
*# You will be redirected back to the registration website [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu/] |
|||
*# Select '''bwUniCluster Service Description''' (on the left hand side) |
|||
*# Click '''Register''' |
|||
*# Finally |
|||
*#* for all non-KIT members '''mandatorily''' set a service password for authentication on bwUniCluster |
|||
*#* for KIT members '''optionally''' set a service password for authentication on bwUniCluster |
|||
<!-- old description |
|||
** login with your home-organizational user account and user password, |
|||
** select service '''''bwUniCluster''''' (on the left side) and |
|||
** follow the instructions to complete the registration. |
|||
--> |
|||
<br/> |
|||
== Changing Password == |
|||
By default, for KIT members your bwUniCluster '''password''' to log on matches that one of your KIT |
|||
account, while for all non-KIT members your bwUniCluster '''password''' is that one you saved during the web registration (compare step 7 of chapter 1.2). |
|||
At any time, you can set a new bwUniCluster password via the registration website [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu] by doing 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 '''Dienstpasswort setzen''' |
|||
# 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 |
|||
<br> |
|||
== Contact == |
|||
If you have questions or problems concerning registration, please [[BwUniCluster_Contact_and_Support#Registration|contact your local hotline]]. |
|||
<br> |
|||
= Login = |
|||
After finishing the web registration '''''bwUniCluster''''' is ready for your '''SSH''' based login. |
|||
'''''bwUniCluster''''' has 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. |
|||
A connection to '''''bwUniCluster''''' can be established by the command: |
|||
<pre> |
|||
$ ssh <UserID>@bwunicluster.scc.kit.edu |
|||
</pre> |
|||
If you are using '''OpenSSH''' (usually installed on Linux based systems) and you want to use a GUI-based application on '''''bwUniCluster''''' you should use the |
|||
''ssh'' command with the option ''-X'' |
|||
<pre> |
|||
$ ssh -X <UserID>@bwunicluster.scc.kit.edu |
|||
</pre> |
|||
== About UserID / Username == |
|||
'''<UserID>''' of the ssh command is a placeholder for your '''''username''''' at your home |
|||
organization together with a '''''prefix''''' as followed: |
|||
* Freiburg: <UserID> = fr_username |
|||
* Heidelberg: <UserID> = hd_username |
|||
* Hohenheim: <UserID> = ho_username |
|||
* KIT: <UserID> = username ''(without any prefix)'' |
|||
* Konstanz: <UserID> = kn_username |
|||
* Mannheim: <UserID> = ma_username |
|||
* Stuttgart: <UserID> = st_username |
|||
* Tübingen: <UserID> = tu_username |
|||
* Ulm: <UserID> = ul_username |
|||
== Allowed activities on login nodes == |
|||
The login nodes of bwUniCluster are the access point to the compute system and to your bwUniCluster $HOME directory. The login nodes are shared with all the users of bwUniCluster. 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 <span style="color:red;font-size:100%;">'''you must not run your compute jobs on the login nodes'''</span>. Compute jobs must be executed 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 executed to the [[bwUniCluster Batch Jobs|queueing system]]. |
|||
