 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)
