-# Application for Login and Resources
+# Application for HPC Resources
 
-In order to use the ZIH systems installed at ZIH, a project application form has to be filled in.
-The HPC project manager should hold a professorship (university) or head a research group. You may
-also apply for a "Schnupperaccount" (trial account) for one year to find out if the machine is
-useful for your application.
+##### This section provides you with guidelines how to  
+- apply for resources to use the HPC system -> [application workflow](./project_request_form.md)  
+- manage members and their access to the project -> [User management for project leaders](./project_management.md)

+##### Below you will find the information about:
 
-Another possible use case is to request resources for a course.

-## HPC-Login
 
-### Get Access without an existing ZIH Login
+## NHR-center
+In order to use the HPC systems installed at ZIH, it is necessary to apply for the resources.
+The applicant (HPC project manager) is required to have a doctorate/PhD.  
+It is possible to apply to different [project types](/project_request_form.md) depending on the project requirements. 
 
-To use the resources, you need a valid ZIH login. To get a ZIH login and the access to HPC,
-please use the [HPC login application form][2].
+However, the [application workflow](/doc.zih.tu-dresden.de/docs/application/project_request_form.md) is for all types identical.
 
-### Get Access with a valid ZIH Login
+Since 2021, HPC at universities has been restructured by the [NHR network](https://www.nhr-verein.de/).
+The network consists of nine centers, which operate the systems and offer
+a coordinated consulting service on the methodological competence of scientific HPC.
+The aim is to provide scientists at German universities with computing capacity
+for their research and to strengthen their skills in the efficient use of this resource.
+
+
+!!! Info  "Researchers with a doctorate from universities or universities of applied sciences in Germany are eligible to apply"  
+      
+    We particularly invite researchers to apply with
+     research projects related to our focus topics:  
+
+       * Life Sciences
+       * Earth System Science
+       * Methods for big data and data analysis and
+        management
+       * Machine Learning
+       * Tiered storage architectures and I/O optimization
+       * Performance and energy efficiency analysis and 
+       optimization
+       * Research projects not related to our focus topics 
+       but from Universities within Saxony.
+
+    We recommend **all other researchers** to review the
+     focus topics of the remaining 
+    [NHR centers](https://www.nhr-verein.de/anwendungsunterstuetzung) and apply to the most suitable for
+     your research topic.  
+    Working at the specialized NHR center related to your 
+    research topic, provides you with the advantage of 
+    receiving topic specific support.
 
-When you have a valid ZIH login, there are two possibilities for you: Either the manager or
-administrator of a HPC project needs to add you as a member of this project via the
-[manager view](project_management.md), or you have to
-[apply for a project](project_request_form.md).
 
 ## Acknowledgment in Publications
 
+To provide you with modern and powerful HPC systems in future as well, we have to show that these
+systems help to advance research. For that purpose we rely on your help. In most cases, the results
+of your computations are used for presentations and publications, especially in peer-reviewed
+magazines, journals, and conference proceedings. We kindly ask you to mention the HPC resource usage
+in the acknowledgment section of all publications that are based on granted HPC resources of the
+[NHR-center at TU Dresden][4]. 
+
 We kindly ask you to mention the HPC resource usage in the acknowledgment section of all
 publications that are based on granted HPC resources of the TU Dresden.
 
-!!! info "Acknowledgment Examples"
-    We provide some [acknowledgment examples](acknowledgement.md) that show you how to do that.
+We provide some acknowledgment examples below.  
+<br>
+
+**Examples:**
+
+??? note "Standard case"
+
+    The authors gratefully acknowledge the computing time
+    made available to them on
+    the high-performance computer <XY> at the NHR Center of
+    TU Dresden. This center is jointly
+    supported by the Federal Ministry of Education and
+    Research and the state governments
+    participating in the NHR 
+    (www.nhr-verein.de/  unsere-partner).
+
+
+??? note "Two NHR centers"
+
+    The authors gratefully acknowledge the computing time
+    made available to them on
+    the high-performance computers <XY> and <YZ> at the NHR
+    Centers at TU Dresden and <YZ>.
+    These centers are jointly supported by the Federal 
+    Ministry of Education and Research
+    and the state governments participating in the NHR
+    (www.nhr-verein.de/unsere-partner).
+
+
+??? note "German"
+
+    Die Autoren bedanken sich für die ihnen zur Verfügung
+    gestellte Rechenzeit auf
+    dem Hochleistungsrechner <XY> am NHR-Zentrum der TU 
+    Dresden. Dieses wird gemeinsam durch
+    das Bundesministerium für Bildung und Forschung und den
+    am NHR beteiligten
+    Landesregierungen (www.nhr-verein.de/unsere-partner)

+
+
+## Terms of Use
+
+
+!!! attention
+
+    Only the German version of the *Terms of Use* is binding.
+
+These new Terms of Use are valid from April 1, 2018: [HPC-Nutzungsbedingungen_20180305.pdf][1]
+
+The key points are are:
+
+- For support reasons, we store your contact data according to our [identity management system][9].
+  (Will be anonymized at least 15 months after the cancellation of the HPC login.)
+  The data of the HPC project (incl. contact of project leader) will be kept for
+  further reference.
+    -Our HPC resources may only be used according to the project description.
+- Responsibilities for the project leader:
+    - She has to assign a team member with an HPC login as the technical project
+      administrator. She can do this herself if she has a login at our systems.
+    - The project leader or the administrator will have to add/remove members to
+      their project. She has access to accounting data for her project.
+- These issues cover the data storage in our systems:
+    - Please work in the scratch filesystems.
+    - Upon request, the project leader or the administrator can be given access
+      to a user's directory.
+    - The scratch filesystems (`/tmp`, `/scratch`, `/lustre/ssd`) are for
+      temporary use only. After a certain time, files may be removed
+      automatically (for `/tmp` after 7 days, parallel `/scratch`: after 100 days).
+    - Before a user leaves a project the leader/administrator has to store away
+      worthy data. For this, the storage services of ZIH (long term storage,
+      intermediate archive) can be used.
+- Project termination (**new**)
+    - At project's end, jobs cannot be submitted and started any longer.
+    - Logins are valid for 30 more days for saving data.
+    - Hundred days after project termination, it's files will be deleted in
+      the HPC filesystems.
+- The HPC user agrees to follow the instructions and hints of the support
+  team. In case of non-compliance, she can be disabled for the batch system
+  or banned from the system.
+
+- Working with logs and HPC performance data (**new**)
+    - For HPC related research ZIH will collect and analyze
+      performance data. Anonymized, it might be shared with research partners.
+    - Log data will be kept for long term analyzes.
+
+These key points are only a brief summary. If in doubt, please consult the German original.
