</code>

Descend in a directory with a large reported size and repeat until you find large files that are worth taking care of.

<code>.[!.]*</code> makes sure the "hidden" dot files are also checked.

* Inodes:

<code>
du -s --inodes .[!.]* * | sort -n
</code>

This will only count inodes in subdirectories. Also make sure your top-level (e.g. $HOME) directory aren't full with hundred thousands of files:

<code>
ls -1a | wc -l
</code>

K Siegmund: /* Check your Entitlements */

<div style="border: 3px solid #e2e3e5; padding: 15px; background-color: #ffffff; margin: 10px 0;">
The bwForCluster Entitlement is issued by the university you are a member of. It tells the cluster-operator that you are currently a member of this university. It also means that the university checked that your actions comply with the German Foreign Trade Act (Außenwirtschaftsgesetz - AWG) and German Foreign Trade Regulations (Außenwirtschaftsverordnung - AWV) (see [https://www.bwidm.de/attribute.php#Berechtigung eduPersonEntitlement]).
</div>

= Step A: bwForCluster Entitlement =

<div style="border: 3px solid #0066cc; padding: 15px; background-color: #e7f3ff; margin: 10px 0;">
To register for a bwForCluster you need the '''bwForCluster Entitlement''' issued by your university.
</div>

The full name of the entitlement is <code><nowiki>http://bwidm.de/entitlement/bwForCluster</nowiki></code>.

Note that this is the name of an identity management attribute and not a link.

More informations on Entitlements and other attributes in general: [https://www.bwidm.de/dienste.php Entitlement (Dienste)]

== Check your Entitlements ==

First check if you already have the Entitlement, some universities automatically assign the entitlement to some accounts (you must allow that your data is being transferred to that page or your cluster login will also not work):

→ '''[https://login.bwidm.de/user/index.xhtml?show=entitlement&highlight=bwForCluster Registration Server bwForCluster Entitlement Check]'''

Note: if you cannot log in to the registration server at all, some crucial information is missing in the information your home university is transmitting to it. Contact the helpdesk of your home university.

== Request an Entitlement ==

If you need the entitlement, please follow the link for your institution or contact your local service desk if no information is provided:

* [[Registration/bwIDM-Entitlements-Uni-Freiburg|Universität Freiburg]]
* [https://heiservices.uni-heidelberg.de/entitlement Universität Heidelberg] (access only within Uni Heidelberg network)

* [[BwForCluster User Access Members Uni Mannheim|Universität Mannheim]]
* [https://www.hlrs.de/apply-for-computing-time/bwforcluster Universität Stuttgart]
* [[BwForCluster User Access Members Uni Tübingen|Universität Tübingen]]
* [[BwForCluster User Access Members Uni Ulm|Universität Ulm]]
* [[Registration/HAW|HAW BW e.V.]]: Please contact your local service desk

<div style="border: 3px solid #ffc107; padding: 15px; background-color: #fff3cd; margin: 10px 0;">
'''Entitlement Synchronization:'''

After your university assigns the entitlement, it takes some time for it to synchronize across the system.
* '''If the entitlement does not appear within 24 hours,''' contact your local service desk

== Pre-Requisite: Get Cluster Access ==

Follow the registration process for the bwForCluster.

→ [[Registration/bwForCluster|How to Register for a bwForCluster]]

== Pre-Requisite: Know the Workflow of Running Calculations ==

On a compute cluster, you do not simply run log in and your software, but you write a "job script" that contains all commands to run and process your job and send this into a waiting queue to be run on one of several hundred computers.

How this is done is described in a little more detail here: [[Running Calculations]]

== Login to the Cluster ==

Setup service password and 2FA token and login to the cluster. → [[JUSTUS2/Login|Login JUSTUS2]]

== Online Course on Justus2 ==

* → [[BwForCluster_JUSTUS_2_Slurm_HOWTO| extensive Slurm HOWTO on specific tasks]]

== Learn about Scaling your Job ==

How many compute-cores should my job use? This depends on the software and the problem you are trying to solve. But if you use too few cores, your computation may take much too long - if you use too many cores, they will not improve the speed of your computation and all you do by using more cores is wasting compute resources and energy.

If you run hundreds or thousands of similar calculations, you should look at this carefully before starting.

How to do this is described in: [[Scaling]]

Data Transfer/SSHFS

2026-06-17T14:26:17Z

K Siegmund:

Sshfs is a network protocol for mounting data. It uses [[Data Transfer/SFTP|sftp]] under the hood.

== Installation ==

For the necessary installations follow this link:<br /> [https://linuxize.com/post/how-to-use-sshfs-to-mount-remote-directories-over-ssh/ How to use SSHFS to Mount Remote Directories over SSH].<br />
a) '''MacOS after the installation'''<br />
To enable sshfs on your Mac go to: System Preferences -> General tab -> Allow Extensions button<br />
Then follow the instructions that pop up (make sure that you remember the instructions before shutting down your computer).<br />
b) '''Linux installation short commands'''
<ul>
<li>Debian/Ubuntu: <code>apt-get install sshfs</code></li>
<li>CentOS/RedHat: <code>dnf install fuse-sshfs</code></li>
<li>If you want to use /etc/fstab, you can do this with the following entry:
<pre>sshfs#<username>@<hostname>: <your_local_mountpoint> fuse defaults,user,noauto,exec 0 0 </pre></li></ul>

== Usage ==

=== Caveat: Unmounting ===

Note that this creates a virtual drive on your system just as if you would plug in an external drive that stays active until you unmount it. Disk mounts happen on a low level of operating systems, so it is important to unmount the virtual drive cleanly whenever possible.

'''MacOS & Linux:'''<br />
If the connection to the cluster broke and you want to remount, you often have to use umount first. Try to remember to always unmount first before retrying. Otherwise it can happen that unmounting is not possible anymore by cmd. Usually the error message in this case tells you that the process is currently busy and therefore cannot umount.

You should be able to find the process(es) that use the file system with <code>fuser -m <your_local_mountpoint></code> and kill/exit the processes that block unmounting or can kill them directly using <code>fuser -k -m <your_local_mountpoint></code>
In case this fails, you may have to restart your computer which automatically unmounts everything.

<pre>bash
umount -f <localPath>
# For example
umount -f /Users/<username>/Documents/mounted
# or use
fusermount -u <localPath>
</pre>

'''Windows'''
You should be able to click on the drive and choose "eject" or "unmount". If this is not the case, you can use
net use X: /delete
or if this does not work
taskkill /f /im sshfs.exe
(from: [https://stackoverflow.com/questions/62031900/how-to-unmount-close-the-mount-for-sshfs-windows stackoverflow])

=== Windows ===
''Caution: sshfs on Windows doesn't work with 2FA. An alternative is [[Data_Transfer/Rclone | Rclone with sftp]] + [[Registration/SSH | ssh key]].''
<ol style="list-style-type: decimal;">
<li>Go to "This PC" and select "Connect network drive" ("Netzlaufwerk verbinden")</li>
<li>Select a drive (W:) and click on "connect with webpage on which you can save documents and images" (Verbindung mit website herstellen, auf der Sie Dokumente und Bilder speichern können)</li>
<li>Enter the following as address, to connect to the home or root folder:
<syntaxhighlight lang="bash">\sshfs\<username>@<hostname>/</syntaxhighlight>
If you would want to go two folders up, you would add “''../../''” at the end.</li></ol>

=== MacOS & Linux ===

<ol style="list-style-type: decimal;">
<li>Create an empty directory. The cluster/storage folder is going to be mounted to this directory.</li>
<li>Mount a folder from the cluster/storage:
<syntaxhighlight lang="bash"># Home folder

Energy Efficient Cluster Usage

2026-06-16T10:07:25Z

K Siegmund: /* How many and which kind of hardware resources do I require for it */

= Introduction =

Energy consumption of data centers has been increasing continuously throughout the last decade. In 2020, the energy consumption of all data centers in Germany amounted to around [https://www.bundestag.de/resource/blob/863850/423c11968fcb5c9995e9ef9090edf9e6/WD-8-070-21-pdf-data.pdf 3 percent] of the total electricity produced. Accompanying this large energy consumption are large-scale emissions of CO2 to the atmosphere and thus significant contributions to climate change.
To illustrate this, an average compute job running on a single node for one day may easily consume 10 kWh or even more. That translates roughly to brewing 700 cups of coffee.
Assuming that a typical bwHPC cluster has a few hundred compute nodes, this amounts to the energy consumption of a village for each cluster.

Although a large amount of this energy consumption is an intrinsic requirement of running large HPC clusters (even when it's processors are idle, a cluster uses a lot of energy), efficient use of the available resources is important. Using as many resources as possible does not make a power user. Using them wisely does.
In the following, a basic introduction to some of the most important aspects of energy-efficient HPC usage from a user perspective is given.

We can generally distinguish three tasks when optimizing for running HPC jobs efficiently.

→ What do I want to do and why do I need an HPC Cluster for it?

→ How many and which kind of hardware resources do I require for it?

→ How do I optimize my code to use these resources most efficiently?

= What do I want to do and why do I need an HPC Cluster for it? =

The bwHPC clusters are used to almost full capacity, and running a job on an HPC node consumes a lot of energy, as shown above.
Therefore, users are requested to run only necessary jobs.

Please consider testing new setups and their output for validity prior to submitting jobs that require lots of resources. This also includes projects where a lot of (smaller) similar jobs are submitted.

Make sure to double-check your jobs prior to the submission, as having to discard the output data of an HPC project due to faulty input files is wasting a lot of computational resources.

Finally, identifying the specific resource requirements for a given job is important to allocate the optimal amount for your compute job, and to decide if an HPC cluster is needed at all.

= How many and which kind of hardware resources do I require for it =

Resource allocation is a crucial part when working on an HPC cluster.
As this is dependent on both the job as well as the specific cluster hardware and architecture available.

'''A small number of jobs and few resources'''

→ Submit to the scheduler. No extended testing and resource scaling analysis are needed.

'''Medium-sized projects'''

→ Run only necessary jobs: Please consider testing new setups and their output for validity prior to submitting a huge amount of similar jobs

→ Start small: Run your problem on a small set of resources first.

→ Use the proper tools for development: If you develop your own code, please use the proper tools for debugging and parallel performance analysis. See: [[Development#Documentation_in_the_Wiki|Development]].

→ A look at the job feedback can help you determine if you are using the cluster efficiently

'''Large projects'''

→ Same approach as for medium-sized projects.

→ Run a scaling analysis for your project with regard to how many resources work best. See: [[Scaling]].

'''Many short jobs'''

→ Handling via the scheduler is inefficient.

→ Simple parallelization by hand is advisable. See: A basic introduction to [[Development/Parallel_Programming | Parallel Programming]].

= How do I optimize my code to use these resources most efficiently? =

The above recommendations will help use the cluster resources more efficiently.
Regarding software development, power efficiency correlates obviously heavily with '''computing performance''', but also with memory usage, i.e. the amount of memory used, but also memory efficiency.

Here, we have gathered a few results based on other research:
→ Use an efficient programming language such as Rust, C, and C++ -- well any compiled language. Do not use any interpreted language like Perl or Python. Since Machine Learning is a hot topic, this deserves a few words: Any ML-Python code using Tensorflow or other libraries will make heavy usage of NumPy and other math packages, which will use C-based implementations. Please make sure, you use the provided Python modules, which are optimized to use Intel MKL and other mathematical libraries.

→ Analyse memory access patterns

→ For small tight loops checking for locks, use the <code>pause</code> instruction.

= Summary: General Recommendations =

* Choose the most '''efficient algorithms''' for the given problem.
* Run only '''necessary''' jobs: Please consider testing new setups and their output for validity prior to submitting a huge amount of similar jobs.
* Start '''small''': Run your problem on a small number of parallel entities (be it processes or threads) first.
* '''Estimate''' the runtime of the parallel job as '''exactly''' as possible to increase the efficiency of the scheduling of the whole system.
* Use the proper tools for development: If you develop your own code, please use the proper tools for debugging and parallel performance analysis. More information is available on the bwHPC Wiki.
* A look at the '''job feedback''' can help you determine if you are using the cluster efficiently.

Data Transfer/SSHFS

2026-06-03T08:45:06Z

K Siegmund: remove harmful otp-incompatible reconnect flags

Sshfs is a network protocol for mounting data. It uses [[Data Transfer/SFTP|sftp]] under the hood.

== Installation ==

For the necessary installations follow this link:<br /> [https://linuxize.com/post/how-to-use-sshfs-to-mount-remote-directories-over-ssh/ How to use SSHFS to Mount Remote Directories over SSH].<br />
a) '''MacOS after the installation'''<br />
To enable sshfs on your Mac go to: System Preferences -> General tab -> Allow Extensions button<br />
Then follow the instructions that pop up (make sure that you remember the instructions before shutting down your computer).<br />
b) '''Linux installation short commands'''
<ul>
<li>Debian/Ubuntu: <code>apt-get install sshfs</code></li>
<li>CentOS/RedHat: <code>dnf install fuse-sshfs</code></li>
<li>If you want to use /etc/fstab, you can do this with the following entry:
<pre>sshfs#<username>@<hostname>: <your_local_mountpoint> fuse defaults,user,noauto,exec 0 0 </pre></li></ul>

== Usage ==

=== Windows ===
''Caution: sshfs on Windows doesn't work with 2FA. An alternative is [[Data_Transfer/Rclone | Rclone with sftp]] + [[Registration/SSH | ssh key]].''
<ol style="list-style-type: decimal;">
<li>Go to "This PC" and select "Connect network drive" ("Netzlaufwerk verbinden")</li>
<li>Select a drive (W:) and click on "connect with webpage on which you can save documents and images" (Verbindung mit website herstellen, auf der Sie Dokumente und Bilder speichern können)</li>
<li>Enter the following as address, to connect to the home or root folder:
<syntaxhighlight lang="bash">\sshfs\<username>@<hostname>/</syntaxhighlight>
If you would want to go two folders up, you would add “''../../''” at the end.</li></ol>

=== MacOS & Linux ===

<ol style="list-style-type: decimal;">
<li>Create an empty directory. The cluster/storage folder is going to be mounted to this directory.</li>
<li>Mount a folder from the cluster/storage:
<syntaxhighlight lang="bash"># Home folder
sshfs <username>@<hostname>: <localPath>
# subfolderX
sshfs <username>@<hostname>:subfolderX <localPath></syntaxhighlight></li></ol>

=== Undo mounting ===

'''MacOS & Linux:'''<br />
If the connection to the cluster broke and you want to remount, you often have to use umount first. Try to remember to always unmount first before retrying. Otherwise it can happen that unmounting is not possible anymore by cmd. Usually the error message in this case tells you that the process is currently busy and therefore cannot umount. In this case, you have to restart the notebook which automatically unmounts everything.

<pre>```bash
umount -f <localPath>
# For example
umount -f /Users/<username>/Documents/mounted
# or use
fusermount -u <localPath>
```</pre>

= Description =

The [https://www.scm.com/adf-modeling-suite/ ADF Modeling Suite] by [https://www.scm.com/ SCM] (Software for Chemistry & Materials) is a collection of programs for modeling chemical and physical properties of molecules and solids. The suite consists of the following components:

* With help of the graphical user interface '''adfinput''' one can construct molecules, solids and slabs. All kinds of calculational parameters like functionals, basis sets, convergence parameters can be defined as well. The calculation and its parameters can be saved as a ''run''-file which is suitable for inclusion in our queueing system scripts. For details see the [https://www.scm.com/doc/Tutorials/Introduction/Introduction.html Tutorials] of SCM.

* '''adfjobs''' can used for interactive job control. This is intended only for short test jobs running in background for some minutes. For longer jobs one should save the job as ''run''-file which can be called from within a queueing system script. For details see the [https://www.scm.com/doc/Tutorials/Introduction/Introduction.html Tutorials] of SCM.

* [https://www.scm.com/product/adf/ '''adf'''] is a powerful molecular DFT (density functional theory) code applicable in many areas of chemistry and materials science. One strength of ADF is in the field of inorganic chemistry.

* [https://www.scm.com/product/band_periodicdft/ '''band'''] is a DFT code for periodic systems using local slater type orbital basis sets.

* [https://www.scm.com/product/dftb/ '''dftb'''] provides fast approximate methods for studying large molecules and large periodic systems.

* [https://www.scm.com/product/reaxff/ '''reaxff'''] is a bond order based force field program for studying reaction dynamics in large complex systems.

* The [https://www.scm.com/product/cosmo-rs/ '''COSMO-RS'''] method allows to predict thermodynamic properties of solutions and mixtures (LogP, VLE, pKa, ...) based on quantum mechanical data from ADF.

= License and citing =

The ADF program suite is available for all users of the cluster. When you publish any results obtained with the ADF program suite you must cite ADF and the used components properly. Therefore please see the [https://www.scm.com/doc/ADF/Required_citations.html required citations]. Furthermore there might be additional [https://www.scm.com/adf-modeling-suite component specific citations] that can be found in documentation of the individual components.

= Usage =

== Creating input files with adfinput ==

Probably the easiest method to create input files is using the graphical user interface '''adfinput''': First start and connect to a [[Start_VNC_Server_-_bwForCluster_Chemistry_-_3D_Acceleration|3D-accelerated VNC session]] via TigerVNC running on one of our visualization nodes.

See: [[JUSTUS2/Visualization]]

Then - within the VNC window - load the adf module and run adfinput with 3D acceleration:
<pre>
module load chem/adf
vglrun adfinput
</pre>

With help of ADFinput molecules and periodic systems can be constructed (depending on the selected target program, i.e. '''adf''' or '''band'''). Furthermore one can control most calculational parameters like DFT methods, basis sets, convergence criteria, etc. After saving the calculation via '''File -> Save as''' with name '''MY_JOB''', a '''run'''-shell script with name '''MY_JOB.run''' can be found on disk.

This '''run'''-shell script contains the job input and executes the appropriate ADF commands like '''adf''', '''band''', etc (the input is piped via STDIN into those commands). The '''run'''-script can be called from within your ADF queueing system shell script, thus the queueing system shell script still defines the queueing system parameters, manages the temporary directories, loads the module, cleans up after the end of the job, etc).

For an introduction how to use the ADF GUI please follow some of the [https://www.scm.com/doc/Tutorials/Introduction/Introduction.html ADF tutorials]. If you want to change the job input without GUI, you can edit the '''run'''-shell scripts manually. All possible keywords and options are documented in the '''manuals''' sections of the [https://www.scm.com/doc/Documentation/index.html documentation of the individual programs].

== Parallel computing ==

In queueing system scripts the commands '''adf''', '''band''', ... automatically use the cores as specified when submitting the job script. Neither '''mpirun''' nor any further command line options are required.

In case of interactive single-node test jobs one can limit the number of cores via command line option '''-n NB_OF_CORES''', for example '''adf -n 8'''.

== Disk usage ==

Temporary files are stored below directory '''SCM_TMPDIR'''. Typically this environment variable is defined within the queueing system script and points to some node-local directory below '''TMPDIR'''. In case of multi-node jobs, '''SCM_TMPDIR''' must point to the same directory on every node and must exist on every node.

When loading the adf module, '''SCM_TMPDIR''' is defined automatically and usually points to '''TMPDIR'''. When running under control of the queueing system, '''TMPDIR''' is the node-local scratch directory of the job.

Please never put temporary files of ADF on central file systems like '''HOME''' or '''SCRATCH''' or workspaces.

|}

= Description =
'''GaussView''' is an advanced and powerful graphical user interface for [[Gaussian]]. With the aid of GaussView you can
* build, save or load molecular structures (advanced molecule editor)
* prepare Gaussian calculations (create and save Gaussian input files with all parameters)
* monitor progress of running Gaussian calculations (login to the compute node and change to the temporary job directory)
* load, view and analyze results (e.g. visualize 3D ISO surfaces of densities and orbitals, plot IR and Raman spectra)
* setup, visualize and analyze parameter scans
* setup QM/MM calculations
For more information on features please visit GaussView's [http://gaussian.com/gaussview6/ ''GaussView Documentation''] web page.
<br>
<br>

= Usage =

There are two methods to start GaussView remotely on JUSTUS 2:
* '''Remote-VNC''' method (recommended): First set up a VNC (Virtual Network Computing) remote desktop connection to one of the JUSTUS 2 login or visualization nodes. To help you with that we have pre-installed TigerVNC on JUSTUS 2. See the documentation [[JUSTUS2/Visualization]] for details. Thereafter you can open a terminal window in that VNC session, load the GaussView module and start GaussView via command ''gaussview''.
* '''X-forwarding''' method (usually slow): First log in to the JUSTUS 2 login or visualization nodes with X-forwarding enabled (i.e. ''ssh -X''). Then load the GaussView module and start GaussView via command ''gaussview''. Major disadvantage: X-forwarding requires a very fast network connection with low latency. Usually home or Wi-Fi networks are too slow.
<br>
'''NEVER start long running large calculations interactively on login or visualization nodes. Use GaussView to prepare and save the input. Then submit a [[Gaussian]] job with the input created by GaussView.'''

== Parallel computing ==

One can construct/save or start serial as well as parallel jobs with GaussView.
To switch from serial to parallel one has to modify entry ''Shared Processors''
within ''Gaussian Calculation Setup'' window.

Please make sure that the speed up of the calculation is reasonable when requesting
more cores. When doubling the number of cores, the speed up should be at least a
factor 1.7, better 1.8.

Please keep in mind that our Gaussian version is only shared-memory parallel.
Therefore requesting more than one node does not make any sense.

== Loading the module and starting GaussView (within VNC session) ==

The best method to use GaussView is to start it within an interactive
remote VNC session or a (Linux-)System with X-forwarding (e.g.: ssh -X 'your-id'@FQDN-of-cluster.de).
<br>
Details on how to start an interactive VNC session running on a compute node can be found here: [[JUSTUS2/Visualization]]

Within the X11 session open a terminal window (e.g. xterm) and execute:
<pre>
$ module load chem/gaussview
gaussview &
</pre>

The GaussView module automatically loads the corresponding Gaussian module.

[[File:Gaussview.jpg]]
<br>
<br>
See [[#GaussView example session|GaussView example session]] for more infos how to work with the GUI.
<br>
<br>
It is recommended to always specify the full module name including
the version of the module, e.g. specify
<pre>
$ module load chem/gaussview/6.1.1
</pre>
to load version ''6.1.1'' of GaussView.
<br>

== Starting Gaussian jobs interactively via GaussView ==

Within the interactive VNC session running on a compute node
you may start Gaussian jobs locally via ''Submit'' or ''Quick Launch''.
These buttons are located within the ''Gaussian Calculation Setup'' window of GaussView.

If you do so you must make sure that these jobs finish before
the run time of the interactive VNC session ends. Furthermore
your should never occupy more cores (GaussView setting '''Shared Processors''', default 1 core)
than specified when submitting the VNC session (Slurm option '''--ntasks-per-node''', default 1 core).
Finally be aware that your job might get killed if it uses more memory
than requested.

== Submitting Gaussian jobs to the queueing system ==

First you can construct your Gaussian job interactively with GaussView.
When done with setting up of the job, save the Gaussian command file to disk
and submit that *.com file as described in the documentation of [[Gaussian]].
Please read the Gaussian documentation as well and make sure that you
specify reasonable values for the number of cores, memory usage,
disk usage and job run time when submitting the job.

= Examples =

== GaussView example session ==

* When 'gaussview' is started, the [[#Loading the module and starting GaussView (within VNC session)|'Builder Fragment']] of the programs main window (gray background) displays the 'Carbon Tetrahedral' by default.
* Click in the middle of the construction window (blue background). The selected fragment should now be displayed there (undo clicks via 'Menu: Edit -> Undo').
* Start a Gaussian calculation 'Menu: Calculate -> Gaussian Calculation Setup'. Keep all defaults and hit 'Button: Quick Launch' at the bottom.
* View the results via 'Menu: Results -> Summary'.
* Create orbital contour plots via 'Menu: Results -> Surface/Contours', 'Button: Cube Actions -> New Cube', 'Button: Surface Actions -> New Surface'. If you have accepted all defaults, you should see the HOMO orbital now.

K Siegmund: /* Register a new RV */

= Step B: Apply for a Rechenvorhaben/Project =

'''Rechenvorhaben/Projects (RV)''' are required for assignment to a bwForCluster.
[[File:RV-my.png|right|frame|My RVs.]]

To get access to an RV, answer the following question:
* Does your work group (or the collaborative project that you are part of) already have an RV?
** '''Yes → [[#Become_Coworker_of_an_RV|Become Coworker of an RV]]'''
** '''No → [[#Register_a_new_RV|Register a new RV]]'''

You can see your RV memberships at the central application site ZAS under [https://zas.bwhpc.de/shib/en/info_rv.php '''My RVs'''].

== Become Coworker of an RV ==

|style="padding:5px; background:#cef2e0; text-align:left"|
[[Image:Attention.svg|center|25px]]
|style="padding:5px; background:#cef2e0; text-align:left"|
You can only sign up for an RV once.
If you are an inactive member of an RV, either because you de-registered yourself or a manager deactivated you, only an RV manager can reactivate you.
|}

The "RV responsible" will provide you with the following data on the RV:
* RV acronym
* RV password

If this information is lost, please let the "RV responsible" [[Registration/bwForCluster/RV/Management#Renew_RV_Password|renew the password]] for the RV.

To become coworker of an RV, follow these steps:
# Please visit the [https://zas.bwhpc.de/shib/en/bwforcluster_collaboration.php '''RV collaboration'''] web form at the [https://zas.bwhpc.de ZAS].
# Select your home organization from the list on the main page and click '''Proceed''' or '''Fortfahren'''.
# You will be directed to the ''Identity Provider'' of your home organization. Enter the username and password of your '''home organization''' (usually these credentials are also used for other services like email) and click '''Login/Einloggen'''.
# You will be redirected back to the RV collaboration form '''https://zas.bwhpc.de/shib/en/bwforcluster_collaboration.php'''.
# Enter '''RV Acronym''', '''RV Password''' and '''Institute''' into the form and check both "Terms of Use". Click '''Send'''.
# You will be assigned to the RV as a new member.
<div style="padding-left:18px;">
[[Image:Attention.svg|left|15px]]
In case of the <span style="color:red;">error</span> "This project is not currently renewed", please ask the RV responsible to apply for a prolongation of the RV. As soon as the prolongation was accepted, you can join the RV.
</div>

After submitting the request you will receive an email from ZAS about the further steps.
RV owner and RV managers will be notified automatically.

== Register a new RV ==

|style="padding:5px; background:#cef2e0; text-align:left"|
[[Image:Attention.svg|center|25px]]
|style="padding:5px; background:#cef2e0; text-align:left"|
An RV is valid for '''one year'''.
After that, the RV responsible must apply for an extension of the RV for it to be renewed for another year.
|}

An RV should be registered by a leader or senior scientist of a research group/collaboration.
You will be:
* held accountable for the coworkers in the RV
* asked to provide information for the two reports required by the DFG for their funding of bwForClusters
* must make sure publications that used bwHPC resources properly cite the use in the [[acknowledgement]]
* must report publications which used bwHPC resources at least once a year
* likely asked for a contribution to a future DFG grant proposal for a new bwForCluster in your area of research ("wissenschaftliches Beiblatt")

'''Some hints:'''
* To be notified about important issues via the cluster's mailing list, it is necessary to finish all three registration steps. If you don't plan to work with the cluster yourself, we recommend to either register nevertheless or ask a colleague who is going to use the cluster to keep you updated. For better transparency, that colleague could receive the ''RV manager'' role from you.
* Any number of coworkers can join the RV to work with the cluster.Therefore, they need to be provided with the RV password and acronym.
* The [https://www.bwhpc.de/bwhpc-domains.php research area] of the group as well as the software and hardware requirements are taken into account.
*: Please look carefully through the scientific fields and research domains to find the field that fits best to your research focus and experience. This way, you'll be assigned to the cluster that can support you best. If in doubt, you can check the [https://www.dfg.de/resource/blob/175334/89ba4a3464c99aaea40fdef47367e7b2/fachsystematik-2020-2024-de-grafik-data.pdf DFG classification] as well.
* Creating mutiple RVs on the same cluster is not necessary. Being part of multiple RVs on the same cluster does not bring any advantages regarding available computing resources. The RV description and resource specifications are important for finding the best fitting cluster. But they don't set any limits. Every cluster user has full access to all cluster resources. And not all research topics must match the RV description. But we appreciate it if you update the RV information whenever you fill in a prolongation application.
* Getting access to two different clusters is only possible if specific software or hardware needs demand access for both.

[[File:RV-reg.png|right|frame|Register a new RV.]]
[[File:BwIDM-login.png|right|250px|thumb|Select your home organization]]
'''To apply for a new RV, follow these steps:'''

# Please visit the [https://zas.bwhpc.de/shib/en/bwforcluster_proposal.php '''RV registration'''] web form at the [https://zas.bwhpc.de ZAS].
# Select your home organization from the list on the main page and click '''Proceed''' or '''Fortfahren'''.
# You will be directed to the ''Identity Provider'' of your home organization. Enter the username and password of your '''home organization''' (usually these credentials are also used for other services like email) and click '''Login/Einloggen'''.
# You will be redirected back to the RV registration form '''https://zas.bwhpc.de/shib/en/bwforcluster_proposal.php'''.
# Fill in all mandatory fields of the form and tick the two "Terms of use". Detailed information on the individual fields can be found in the section [[Registration/bwForCluster/RV#Registration_Form_Details|Registration Form Details]]. Click '''Preview'''.
# If the information is correct, click '''Submit''', otherwise you can customize your application.
# Go to section [[Registration/bwForCluster/RV#Registration_Response|Registration Response]] for the next steps.

Please note that for your convenience you can also switch to the [https://zas.bwhpc.de/shib/bwforcluster_proposal.php German version] of the web form.
The submitter of the RV will be assigned the role "RV responsible" (see [[Registration/bwForCluster/RV/Management|Roles in an RV]]).
