Upd:Linux-Cluster: Completion of ICE maintenance delayed

[LRZ aktuell]

 Changes to this message: Maintenance extended
Update: Due to the large workload involved in integrating the new
 resources into the Linux cluster, as well as the personnel vacation
 situation at LRZ, returning the sgi ICE system to user operation is
 delayed.We hope to start production again on September 7 (this target
 date has also been updated below). Please note that the new MPP cluster
 has been opened for general user operation, and provides resources on a
 larger scale than the ICE. Submission of batch jobs is documented in
 http://www.lrz.de/services/compute/linux-cluster/batch_parallel/
 -----------------------------------------------------------------------
 The SGI ICE system will be unavailable for regular user operation
 between 22nd and 7th of September, 2011. This is due to an operating
 system and batch queueing upgrade. After this extended maintenance, the
 system will be run in a SLURM cell of the Linux Cluster; please consult
 the cluster documentation at http://www.lrz.de/services/compute/
 linux-cluster/ for upcoming details on this new batch software deployed
 on the parallel segments of the LRZ cluster. Submission of SGE jobs to
 the ICE will not work anymore after the upgrade.
 
 After the upgrade, it is recommended that you perform the following
 measures:
 
   * recompile and relink your programs using the new sgi MPT release
   * modify your batch scripts to use SLURM instead of SGE
