SuperMUC interruption of operation Nov. 19 28
by LRZ aktuell Nov. 9, 2012

Nov. 9, 2012

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, approximately 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.

Upd:SuperMUC: returning to user operation
by LRZ aktuell Nov. 5, 2012

Nov. 5, 2012

Changes to this message: Returning to user operation Update (Nov 5, 18:05): Thanks to the concerted efforts of IBM and Mellanox, the problems resulting from last week's firmware update have been resolved. The system has been returned to regular user operation. ----------------------------------------------------------------------- Between October 29, 8:00 and October 31, 18:00 the system will 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. The following items are of particular interest: * IBM PE 1.2 PTF9. This update fixes a memory leak in the IBM MPI library as well as some problems with MPI-IO. Please remove any MP_MPILIB=pempi and/or MP_SHARED_MEMORY=no workaround settings from your LoadLeveler scripts, recompile, relink and rerun your application and check whether the problems are solved. Please provide feedback if this is not the case. * An update for the GPFS file system (although it is not expected that this update will solve all outstanding I/O problems). * Intel compilers (from 12.1.5 to 12.1.7 for the default release, and 13.0 Update 1 is available as a non-default release) * Intel MKL update (from 10.3u9 to 10.3u13) This information is also available on our web server http://www.lrz-muenchen.de/services/compute/supermuc/aktuell/ali4438/ Reinhold Bader
