Changes to this message: Update Upd: Dear users of the SuperMUC Petaflop system at LRZ, the scheduled maintenance is finished and the system is back in operation. More details about changes in the work environment will follow. Thanks for your patience! ----------------------------------------------------------------------- Dear users of the SuperMUC Petaflop system at LRZ, due to a scheduled maintenance the system will become temporarily unavailable for user operation from June 24, 8:00 am onward. Because we are preparing to improve the energy efficiency of the system, calibration runs will need to be performed in addition to software updates. Therefore, this maintenance is expected to last four days. A list with the changes to the system software will be published via this document once ready.
