HPERM to GPERM migration
[3268] Aug 03, 2018

Dear HLRN user,

this message contains the steps you need to take in order to ensure
access to data stored in PERM Hannover (hperm). It also contains
information on the use of the new archival facilities in Göttingen.

  1. All data from PERM Hannover (hperm) will eventually and
    automatically be transferred to the new system in Göttingen
  2. Contents of the archive in Hannover will be frozen on August
    8th, 2018 at noon (next Wednesday 12:00). HLRN Hannover and the
    PERM servers in Hannover will go out of service August 31st, 2018.
  3. You can still read from hperm after August 8th until the final
    shutdown of the servers in Hannover, but access will be read-only.
  4. Due to the nature of the archive media (tapes), it may take up
    to three months until hperm data will become available again in
    gperm. Data in hperm will not be accessible between shutdown of
    PERM Hannover and completion of the migration.
  5. If you need data that is stored in hperm during the interim phase,
    you should copy these files to gperm until the end of August.
    Please make sure you only copy what you need during the transition
    and start at your earliest convenience.
  6. New data should already go to the archival system at Göttingen
    (gperm), even if it is created in Hannover. So check/change your
    job scripts.

    Documentation on how to access gperm can be found here:


In case you have any questions, do not hesitate to ask for support.

HLRN-IV User Training Workshop October 08-11 in Göttingen
[3263] Jul 31, 2018

Dear HLRN users,

this September the first phase of the HLRN-IV will start its operation in Göttingen. To familiarize users with the changes and improvements in HLRN-IV, a training course will be held in Göttingen.

The following topics will be discussed during the course:
  • Introduction to the new system (architecture, hardware, software)
  • Intel software and performance analysis tools
  • The new batch system SLURM
  • Hands-on exercises
The training course will be from October 08th, 11:00, until October 11th, 12:00 and will take place in Göttingen.

Due to a number of other conferences and exhibitions in the Göttingen area during the time of the workshop, hotels are in high demand. We advise to book your rooms as early as possible.

More details about this course, registration, and accomodation etc. are available at our workshop website.


Apply for Computing Time by July 28th, 2018
[3259] Jul 05, 2018

The Scientific Board of the HLRN is inviting project proposals applying for computing time on the HLRN system.

The next deadline is July 28th, 2018, at 23:59.

Projects that need more computing time than 10,000 NPL resource units per quarter are invited to submit a project proposal ("Großprojektantrag") to the Scientific Board ("Wissenschaftlicher Ausschuss") of HLRN for the next quarterly review. Resources are allocated for one year starting October 1st, 2018, on a quarterly basis after review of the proposal (see the Application HowTo and the Scientific Board portal page). Notifications will be sent out in mid-September 2018.

In 2018 HLRN allocates about 130 million core hours per quarter (equivalent to about 42 million NPL per year) to successful proposals.
Please note: The project abstract has to be created in a certain format. The appropriate HLRN LaTeX template can be downloaded from the HLRN web page "required documents". The use of this template is required.

In case of questions, please contact your local HLRN support person or your HLRN project consultant before submitting the proposal.
