BwForCluster User Access

The usage of bwForCluster is free of charge. bwForClusters are customized to the requirements of particular research areas.

bwForClusters are 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:

1. Registration of a new or joining an already existing rechenvorhaben (RV) at "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.
2. Application for a bwForCluster entitlement issued by your university.
3. Personal registration at assigned cluster site based on approved RV and issued bwForCluster entitlement .

Step 1 and 2 can be done in parallel. 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 on ("ZAS").

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 it again.

Register a new RV

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

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 the grant proposal for a new bwFor cluster of the same research area

Please follow the steps at bwForCluster RV registration

Become Coworker of an RV

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

• acronym
• password

of the RV

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.

Response

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

Issuing bwForCluster entitlement

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

How to get an entitlement is described at the separate page BwForCluster_Entitlement

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):

Cluster topic and location	Registration server
bwForCluster Chemistry JUSTUS Ulm	http://bwidm.rz.uni-ulm.de
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

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.

  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 ~15 minutes before trying).
