 -----------------------------------------------------------------------
 Dear users of the SuperMUC petascale system at LRZ,
 
 Due to a combined hard- and software maintenance, SuperMUC will be
 unavailable for user operation between January 28, 8:00 and the
 afternoon of January 31. Jobs still running at the beginning of the
 maintenance will be cancelled.
 
 The following changes are introduced by this maintenance:
 
   * Access to the PRACE network will become available to PRACE users,
   * LoadLeveler mail notification will be activated,
   * Licence servers will be accessible from the compute nodes,
   * The Infiniband software stack will be updated to a newer release,
   * Some presently missing packages will become available on the
     compute nodes (e.g., you can remove the workaround for a missing
     libnuma.so)
