Changes to this message: Update 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. For * all systems in the Linux Cluster * 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 was completely retired from user operation since it had reached the end of its lifetime. * 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. I.e., * supzero: /home/hlrb2/projectID/userID will be changed to /home/hpc/ projectID/userID * Linux Cluster: /home/hlrb2/projectID/userID will be changed to / home/hpc/projectID/userID We will provide softlinks in the file system so that all your jobs and scripts should still work. However for the future and for the purpose of archiving we urge you to change these. A general advice is not to use absolute pathes for filenames but the HOME-variable.
