SuperMUC: Interruption of batch processing July 9-11

[LRZ aktuell]

Dear users of the SuperMUC Petaflop System,
 
 due to a scheduled block operation phase, SuperMUC will not be
 available for general batch processing between Tuesday, July 9, 8:00
 and Thursday, July 11, 18:00. On Tuesday, approximately half the
 machine will be flushed, the other half will be flushed early on
 Wednesday. Flushed jobs for which the default rerun policy was
 specified, or for which restart is explicitly requested, will restart
 after the block operation phase is concluded.
 
 Login to the front end and submission of small jobs to the test queue
 will continue working during this period. The migration system supzero
 is not impacted by the interruption.
 
 The purpose of the block operation is focused work on scaling up
 selected simulation programs to the complete machine in the context of
 an Extreme Scaling Workshop; LRZ thanks IBM and Intel for providing
 specialist support for this opportunity.
