23rd Gauss Call for Large-Scale Projects

Users with huge requirements of computing time must submit their
proposals via the Gauss Calls. The current 23rd Gauss Call is open from

January 13th to February 10th 2020, 17:00 o’clock CET (strict deadline)

The call will cover the period 1 May 2020 to 30 April 2021.

  • Projects, which need more than 45 million core-hours per year on
    SuperMUC-NG, must apply through this call.
  • LRZ provides a total of 600 Mio core-hours for this call.

Further information:::

Change of Access Policy for the tape archive

Due to changed technical specifications for the IBM Spectrum Protect software, we have to change the access policy for the tape archive on SuperMUC-NG.
This will also affect data from SuperMUC, which have already put into the tape archive.

  • Permissions to access the data will now be granted to all users of a project i.e., all users in a project group can retrieve data from other users in this project group.
  • The previous policy was that only the users who wrote the data into the archive could access it.
  • If your project is ‘pr12ab’, you can see the members of this group by
    getent group pr12ab-d
  • You have to add the project in the dsmc commands  i.e.
    dsmc q ar “/gpfs/work/p12ab/us12ab5/*“ –se=p12ab
  • Please note the difference between the project (“pr12ab”) and the permission group for data (”pr12ab-d”)
