All HPC Systems: Interruption of user operation / storage maintenance

Dear users of the HPC systems at LRZ,
As part of its continuing efforts to provide ever increasing reliable
and fast storage capacity to its HPC users, LRZ has installed new
network attached storage devices which will be taken into user
operation in early November. Changing over to this new storage area,
which will comprise all HPC user's home directories, necessitates an
interruption of operation on all HPC systems.
1. all systems in the Linux Cluster,
2. the supzero migration system,
user operation will be suspended on Friday, October 28 at 10:00 am. It
is expected that most systems will go online again in the afternoon of
November 2, 2010. The following exceptions should be noted:
* HLRB-II is completely retired from user operation since it has
reached the end of its lifetime. All HLRB-II users must henceforth
process their jobs on supzero.lrz.de. See also http://www.lrz.de/
services/compute/hlrb/aktuell/ali4107/ for further details.
* the new MEGWare MPP cluster will undergo a prolonged maintenance
because it is intended to move the system into a different computer
room which can provide the advanced cooling technology for which
the system has been designed in order to achieve optimal energy
efficiency. Therefore, the MPP system will be unavailable between
October 26, 10:00 am and November 11.
Important Note: After the maintenance, the path name for your HOME
directory will be changed to start with /home/hpc. If batch (or other)
scripts do not reference the home directory via the $HOME environment
variable they will need appropriate changes. This name change also may
cause queued jobs to fail if they are started after the maintenance.
