Upd:SuperMUC interruption of operation Nov. 19 - 28

[LRZ aktuell]

 Aenderungen an der Mitteilung: Returned to user operation
Update (Nov 28 9:05):
 
 The system has been returned to user operation: Login is possible
 again, and the queues are running. Please also note that the following 
 new functionality is now available:
 
   * Intel MPI version 4.1 now works
   * TSM archiving is possible by logging in to supermuc-tsm.lrz.de.
     Please note that these special purpose nodes should be used only
     for archiving and retrieving data with TSM. Please do not use them
     to compile or run other programs, or to submit LoadLeveler jobs.
 
 Unfortunately, there still seem to occur occasional link failures that
 are not caught by the monitoring or the software, leading to occasional
 job failures. We are interested in obtaining feedback about failure
 rates - please report via the service desk, specifying job size in
 nodes or cores and percentage of failure with respect to number of
 jobs.

 Dear users of the SuperMUC petaflop system at LRZ,
 
 It has turned out that the electrical infrastructure that powers the
 system contains defective parts that need to be replaced.
 Unfortunately, this implies that electrical power must be shut off
 completely for a few days.
 
 Furthermore, LRZ needs to fulfill contractual obligations which involve
 measuring the energy consumption of specially chosen benchmarks on the
 complete system. These runs also need a few days of uninterrupted usage
 of the complete system.
 
 Therefore, the system will be unavailable for regular user operation
 between Sunday November 18, at 12:00 and November 28. If any further
 delays occur due to unforeseen side effects of the electrical works, we
 will keep you updated via this document.
