The usage of bwForCluster is free of charge. bwForClusters are customized to the requirements of particular research areas.
Each bwForCluster is/will be financed by the DFG (German Research Foundation) and by the Ministry of Science, Research and Arts of Baden-Württemberg based on scientifc grant proposal (compare proposals guidelines as per Art. 91b GG).

Granting user access to a bwForCluster requires 3 steps:

# Registration of a new or joining an already existing ''Rechenvorhaben (RV)'' at [https://www.bwhpc-c5.de/en/ZAS/zas_uebersicht.php "Zentrale Antragsseite (ZAS)"]. An ''RV'' defines the planned compute activities of a group of researchers. As coworker of this group you only need to register your membership in the corresponding ''RV''.
# Application for a [[#Issueing bwForCluster entitlement | bwForCluster entitlement]] issued by your university.
# [[#Personal registration at bwForCluster | Personal registration]] at assigned cluster site based on approved ''RV'' [[File:Zas assignment icon.svg|25px|]] and issued bwForCluster entitlement [[File:bwfor entitlement icon.svg|25px|]].

<br>
Step 1 and 2 are pre-steps and requirements of step 3. Moreover, steps 1 and 2 can be done in parallel. The question, at which bwForCluster site to do step 3, will be answered by the cluster assignment team (CAT) based on the data of step 1, i.e. at ''ZAS''.


= RV registration at ZAS =

The ''rechenvorhaben'' (RV) registration at ZAS does '''NOT''' correspond to typical compute project proposals as for other HPC clusters, since:
* there is no scientific reviewing process
* the registration inquires only brief details and
* it covers a group of coworkers, and
* only the '''''RV''''' responsible must submit the ''rechenvorhaben''.
<br>

== How to register? ==
=== RV ===
Typically only the leader of a scientific work group or the senior scientist of a research group/collaboration needs to login at
* https://www.bwhpc-c5.de/en/ZAS/bwforcluster_rv_registration.php
and to fill in all mandatory fields of the given web form. Please note that for your convenience you can also switch to the [https://www.bwhpc-c5.de/ZAS/bwforcluster_rechenvorhaben.php german version] of the web form. The submitter of the '''''RV''''' will be assigned the role '''RV responsible'''.

The web form consists of the following '''fields''' to be filled:

= Issueing bwForCluster entitlement =

Each university issues the bwForCluster entitlement
<pre>http://bwidm.de/entitlement/bwForCluster</pre>
only for their own members.

The bwForCluster entitlement issued by a university assures the operator of a bwForCluster that its university member's compute activities comply with the German Foreign Trade Act (Außenwirtschaftsgesetz - AWG) und German Foreign Trade Regulations (Außenwirtschaftsverordnung - AWV).

The following unversities have already established a process to issue the bwForCluster entitlement:
* [http://www.scc.kit.edu/downloads/sdo/Antrag_Zugangsberechtigung_bwForCluster_v2.pdf KIT]
* [[BwForCluster User Access Members Uni Ulm|Ulm University]]
* [[BwForCluster User Access Members Uni Tübingen|Tübingen University]]
If you do not find your university in the list above, please contact your local service desk.

= Personal registration at bwForCluster =

Once you have registered your own RV (''rechenvorhaben'')
or a membership in an RV, the cluster assignment team will provide
you with information about your designated cluster. You will receive
an email with a website to create an account for yourself
on that cluster.

Available bwForCluster registration servers (service providers):

Please note, this step is different to your registration at ZAS since
here you register yourself as a person. Only based on your personal credentials
a user account can be generated. However, resource requests of the RV in ZAS
will be cross-checked with the resources consumed by you and your RV coworkers
on this cluster.

After steps 1 and 2 (RV approval and bwForCluster entitlement) please visit the

* bwForCluster ''service provider'' registration website (see table above or email after RV approval):
*# Select your home organization from the list of organizations and click '''Proceed'''.
*# You will be redirected to the ''Identity Provider'' of your home organization.
*# Enter your home-organizational user ID (might be user name, email, ...) and password and click '''Login''' or '''Anmelden'''.
*# When doing this for the first time you need to accept that your personal data is transferred to the ''service provider''.
*# You will be redirected back to the cluster registration website.
*# Select '''Service Description''' of the designated cluster.
*# Click on '''Register''' link to register for this cluster.
*# Read and accept the terms and conditions of use and click on button '''Register'''.
*# Finally you will receive an email with instructions how to login to the cluster (please wait ~15 minutes before trying).
*# Optionally but strongly recommended: Click on '''Set Service Password''' and set a password for the cluster.

= Login to bwForCluster =

Personalized details about how to login to the cluster are included
in an email send after registration at the bwForCluster service provider.
