Dear users of the SuperMUC petaflop system,
 Strong performance variations and hangs of I/O, which have also been
 observed by regular production programs on the systems, have caused the
 acceptance step for GPFS performed on December 11 to fail.
 For this reason, LRZ has decided to turn over the complete system to
 IBM for an open ended analysis phase beginning on Saturday, December
 15, at 12:00
 LRZ is of the opinion that there is no alternative to this procedure in
 order to isolate and remove the cause for the observed problems on the
 system and obtain more stable user operation in the long term. We will
 inform you via this document once a date for returning to user
 operation has been fixed.

 This information is also available on our web server
