Aenderungen an der Mitteilung: Prolongation of maintenance Update (October 11, 17:30) Unfortunately there still are issues with the SLURM configuration of the serial cluster parts, so we need to prolong the maintenance until these problems have been resolved. We'll keep you updated on the progress via this document. ----------------------------------------------------------------------- Dear users of the Linux Cluster Systems at LRZ, The overdue operating system update of the serial segment has been scheduled for October 8, 8:00 am - October 11, 6:00 pm. At the beginning of this maintenance, all SGE jobs that are still running will be deleted. All queued jobs that target the systems to be upgraded will be lost. During the above interval, the cluster will not be available for user operation. After return to user operation, you will need to change your SGE job scripts over to using SLURM; documentation on how to use SLURM for serial jobs will be published on the LRZ web server and linked from here as it becomes available. Generally, it may also be necessary for you to re-compile your applications for the new environment. Also note that access to the cluster login node lx64ia2 will already become unavailable on October 2; please use the remaining login node lx64ia3 in the meantime. The secure shell keys for all login nodes may become invalid and will be updated on the LRZ web server if that is the case.
