The first step to become a user on the HLRN system is to apply for a user account on the HLRN service portal. Holding an account you can
- perform test simulations to prepare project proposals and
- submit proposals for compute projects on the HLRN service portral.
In the course of the account establishment two support members are assigned to you, a local consultant and a scientific consultant. National and international regulations limit access to the HLRN system for people originating from certain countries. For details, please read the document Supercomputer und Exportkontrolle of the BMBF and the information on the service portral.
Lifetime of a user account
As long as an account is a member of a compute project, the lifetime of this account does not finish. If an account if newly established or if the membership in the last compute project has finished, then the lifetime of the account is three quarters. Following this period access to the data of the account is possible during a fourth quarter. After the end of this fourth quarter the user account is disabled. In reasonable and exceptional cases, the lifetime of a user account can be extended. For that please contact your consultant.
Compute time of a user account
Holding a user account you are able to work on the HLRN system and to expend compute time. Each user account has its own contingent holding 10,000 NPL per quarter. NPL is the abbreviation for “Norddeutsche Parallelrechner-Leistungseinheit” and it is defined on the page Accounting of the user documentation. Additionally to this contingent of the account, access to all contingents of compute projects is possible in which the account is a member in. In reasonable and exceptional cases, the contingent of a user account can be extended. For that please contact your consultant.
Further hints about user accounts you find on the page Hinweise und Policies zum Service Portal of the user documentation.
