Changes to this message: Returning to user operation Update on status: The NAS maintenance has been successfully concluded; however returning the HPC cluster systems to user operation is a bit delayed: The MPP, Myrinet, ICE and serial cluster segments are available again, but the UV systems are still in maintenance. Also, the visualization systems GVS3 and GVS4 are not yet in operation. For the status of SuperMIG please see the separate notification. ----------------------------------------------------------------------- Dear users of SuperMIG as well as the Cluster systems, in its ongoing effort to increase the storage capacity and performance on its HPC systems (and especially the new Petascale system that is being prepared for user operation), LRZ has taken new NAS systems into operation. Presently, LRZ is transferring the data on all HOME directories to the new system. In order to take the final step in switching over regular operations, an interruption of services on all HPC systems is necessary. Therefore, on June 18 between 8:00 am and 3:00 pm no user operation will be possible on the Linux Cluster as well as the SuperMIG migration system. Since a reboot of all systems is needed, running jobs will be removed and may require a resubmission.
