Upd:SuperMUC: scheduled maintenance Oct. 29-30

[LRZ aktuell]

 Changes to this message: Maintenance delayed from original schedule
Dear users of SuperMUC, it has turned out that the needed maintenance
 measures not onlv involve updates on the compute nodes, but also in the
 storage and configuration infrastructure. Therefore we have decided to
 postpone the maintenance, as well as to extend it from one to two days.
 
 Between October 29, 8:00 and October 30, 18:00 the system will
 therefore be unavailable for user operation. During this maintenance
 configuration changes and software updates will be installed which
 should improve stability of both Intel and IBM MPI operation. An update
 for the GPFS file system will also be installed (although it is not
 expected that this update will solve all outstanding problems).
