= Registration =
 
 
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 members. Details on the issuing process and/or the entitlement application forms are listed hereafter:

* Hochschule Reutlingen
 
* Hochschule Rottenburg
 
* Hochschule Stuttgart (HfT)
 
* Hochschule Ulm
 
<br>
 
 
== Step B: Web Registration ==
 
After step A, i.e., after issueing the bwUniCluster entitlement, 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/]
 
*# <div>Select unter '''The following services are available''' the service '''bwUniCluster''' <br>[[File:bwRegWebApp_avail_services_pic01.png|center|border|]]</div>
 
*# 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.

== Step C: <span style="color:red;font-size:100%;font-weight:bold">Amendment:</span> bwUniCluster questionnaire ==
 
Starting June 1st, 2015, usage of bwUniCluster mandatorily requires the
 
questionnaire
 
 
https://zas.bwhpc.de/shib/en/bwunicluster_survey.php
 
 
to be answered. The input is solely used for the
 
elaboration of future support activities and for planning future HPC
 
resources. From June 1st, 2015, login to bwUniCluster 2.0 is only permitted
 
to users who have already answered the questionnaire. '''''Exception''': For the first 14 days after the web registration login to bwUniCluster 2.0 is permitted without participation in the questionnaire.''
 
<br>
 
<br>
 
 
== Changing Password ==
 
By default, for KIT members your bwUniCluster 2.0 '''password''' to log on matches that one of your KIT
 
account, while for all non-KIT members your bwUniCluster 2.0 '''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 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
 
<br>
 
 
== Contact ==
 
If you have questions or problems concerning bwUniCluster 2.0 registration, please [[Registration_Support_-_bwUniCluster|contact your local hotline]].

= Login =
 
After finishing the web registration bwUniCluster 2.0 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 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
 
</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>
 
 
== Login applications: Windows ==
 
 
=== Hints for using MobaXterm ===
 
 
Note: The bwHPC-C5 support team strongly recommends to use [http://mobaxterm.mobatek.net/ MobaXterm] instead of ''PuTTY'' or ''WinSCP''. ''MobaXterm'' provides a X11 server allowing to start GUI based software.
 
 
Start ''MobaXterm'', fill in the following fields:
 
<pre>
 
Remote name : uc2.scc.kit.edu
 
Specify user name : <UserID>
 
Port : 22
 
</pre>
 
After that click on 'ok'. Then a terminal will be opened and there you can enter your password.
 
 
 
=== Depreciated: Hints for using PuTTY ===
 
Start PuTTY, fill in at window ''PuTTY Configuration'' under category ''Session'' the following fields
 
<pre>
 
Host Name : <UserID>@bwunicluster.scc.kit.edu
 
Port : 22
 
Connection type : SSH
 
</pre>
 
and click on ''Open'', enter your password and accept adding ''host key''. Note that you can also name the configured session via ''Save'' and load it later via the given name.
 
 
 
=== Depreciated: Hints for using WinSCP ===
 
 
Start WinSCP, fill in the following fields:
 
<pre>
 
File Protocol : SCP
 
Host name : bwunicluster.scc.kit.edu
 
Port : 22
 
User name : <UserID>
 
</pre>
 
and click on 'Login' and enter your password. Note that you can also name the configured session via ''Save'' and load it later via the given name.
 
 
== About UserID / Username ==
 
 
'''<UserID>''' of the ssh command is a placeholder for your '''''username''''' at your home
 
organization together with a '''''prefix''''' as followed:
 
 
{| width=450px class="wikitable"
 
! Home organization !! <UserID>
 
|-
 
| Universität Freiburg || ''fr_''username
 
|-
 
| Universität Heidelberg || ''hd_''username
 
|-
 
| Universität Hohenheim || ''ho_''username
 
|-
 
| KIT || username ''(without any prefix)''
 
|-
 
| Universität Konstanz || ''kn_''username
 
|-
 
| Universität Mannheim || ''ma_''username

== 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]].

= Deregistration =
 
If you plan to permanently leave the bwUniCluster 2.0, follow the deregister checklist:
 
# Transfer all your data in $HOME and workspace to your local computer/storage and after that clear off all your data
 
# Visit [https://bwidm.scc.kit.edu/ https://bwidm.scc.kit.edu]
 
#* Select your home organization from the list and click '''Proceed'''
 
#* Enter your home-organisational user ID / username and your home-organisational password and click '''Login''' button
