Upd:SuperMUC: scheduled maintenance Jan 28  31

[LRZ aktuell]

 Changes to this message: Prolongation of maintenance
Update 2 (Jan 31 17:50): Internal testing unfortunately has revealed a
 number of problems that prevent us from returning the SuperMUC system
 to user operation. We intend to provide daily updates on the status of
 the system.
 
 -----------------------------------------------------------------------
 Update (Jan 30 afternoon): In order to check additional hardware and
 firmware modifications that were done to improve the stability of the
 system (see also http://www.lrz.de/services/compute/supermuc/aktuell/
 ali4512/, as well as dedicated operation for a project that requires
 short-term use of the complete machine, user operation of the system is
 delayed to the afternoon of January 31.
 
 -----------------------------------------------------------------------
 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)
