BwForCluster User Access

Granting user access to a bwForCluster requires 3 steps:

1. Become part of an rechenvorhaben (RV) either by joining as a coworker or creating a new one
2. Permission from your university to use a bwForCluster called bwForCluster entitlement
3. Personal registration at the cluster site based on approved RV and issued bwForCluster entitlement .

Step 1 and 2 can be done at the same time. When both are finished, you can do step 3. Which cluster you will get access to depends on your research area and is decided in step 1.

RV registration at ZAS

You will have to register a "rechenvorhaben" in which you shortly describe your group's compute activities and the resources you need. Any amount of co-workers can then join your RV without having to register another RV.

Register a new "RV"

Typically done only by the leader of a scientific work group or the senior scientist of a research group/collaboration.

If you register your own RV, you will be:

1. held accountable for the co-workers in the RV
2. asked to provide information for the two reports required by the DFG for their funding of bwFor clusters
3. likely asked for a contribution to a future DFG grant proposal for a new bwFor cluster in your area of research ("wissenschaftliches Beiblatt")

Please follow the steps at bwForCluster RV registration

Become Coworker of an "RV"

Your advisor (the "RV" responsible") will provide you with the following data on the RV:

• acronym
• password

To become coworker of an RV, please login at

• https://www.bwhpc-c5.de/en/ZAS/bwforcluster_collaboration.php

and provide acronym and password. You will be assigned to the 'RV' as a member.

After submitting the request you will receive an email from ZAS about the further steps (i.e. personal registration at assigned bwForCluster). The RV owner and any managers will be notified automatically. You can see your RV memberships at https://www.bwhpc-c5.de/en/ZAS/info_rv.php

Permission of Your University ("bwForCluster entitlement")

Your own high school or university has to grant you permission to use a bwForCluster.

Getting permission from your university to calculate on bwForClusters is independent of an RV and can be done before or while getting an RV. If you are only creating an RV for your research group but do not plan to use the cluster yourself, you do not need to do this step.

Each university has their own procedure.

The page BwForCluster_Entitlement contains a list of participating high schools and links to instructions on how to get an bwForCluster entitlement at each of them.

Personal registration at bwForCluster

Once you have registered your own RV (rechenvorhaben) or a membership in an RV, you will receive an email with a website to create an account for yourself on that cluster. The email will send you to one of the following Websites:

Available bwForCluster registration servers (service providers):

Cluster topic and location	Registration server
bwForCluster Chemistry JUSTUS 2 Ulm	https://bwidm.scc.kit.edu (registration NOT open yet)
bwForCluster MLS&WISO (Production and Development)	https://bwservices.uni-heidelberg.de
bwForCluster NEMO Freiburg	https://bwservices.uni-freiburg.de
bwForCluster BinAC Tübingen	https://bwservices.uni-tuebingen.de

In this step, a user account will be created at the cluster based on your personal credentials.

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

• bwForCluster service provider registration website (see column registration server in table above or email after RV approval):
  1. Select your home organization from the list of organizations and click Proceed.
  2. You will be redirected to the Identity Provider of your home organization.
  3. Enter your home-organizational user ID (might be user name, email, ...) and password and click Login or Anmelden.
  4. When doing this for the first time you need to accept that your personal data is transferred to the service provider.
  5. You will be redirected back to the cluster registration website.
  6. Select Service Description of the designated cluster.
  7. Click on Register link to register for this cluster.
  8. Read and accept the terms and conditions of use and click on button Register.
  9. Finally you will receive an email with instructions how to login to the cluster (please wait at least 15 minutes before trying).
  10. Click on Set Service Password and set a password for the cluster.
  11. Note: BinAC Tübingen => Users do not set a separate service password and have to use their local account credentials instead.
  12. Note: JUSTUS 2 Ulm => You must set a service password and you must obtain an additional time based one time password (TOTP) as second login factor (for details see below).

Note: You can return to the registration website at any time, in order to review your registration details, change/reset your service password or deregister from the service by yourself.

• JUSTUS 2 Ulm: For better security login to JUSTUS 2 requires two factors. In addition to your SERVICE password a time based one time password (TOTP) is required as second factor:
  1. Use JUSTUS 2 account name and your JUSTUS 2 service password to login to <NOT-SHOWN-YET-AND-HERE>.rz.uni-ulm.de
  2. Follow instructions displayed by the server to install a TOTP app on your smart phone, import the displayed TOTP QR code into the app and save the TOTP key for your JUSTUS 2 account.
  3. Thereafter you can login to JUSTUS 2 (see below) by specifying the time based one time password and your service password.
