Changes to this message: Update Update: The cluster and visualization systems are available again. In the Myrinet segment, quite a number of systems are still offline, but batch processing should work again. The login nodes lx64ia2 and lx64ia3 are available for submission of SGE jobs; however Parastation MPI will not run on lx64ia2 any more. Please login to the MPP cluster and build and run your programs from there as indicated in the cluster docs. ----------------------------------------------------------------------- Dear users of the Cluster systems at LRZ, as announced in http://www.lrz.de/aktuell/ali4261/ user operation on the cluster will be interrupted due to an electrical power shutdown test which affects all storage systems. In order to cleanly shut down all accesses to the storage systems, we have already started to drain the SLURM queues and all running jobs will be removed from 4:30 pm onwards. Please also note that after this interruption, the SGE queues mpi_8, shm_8, mpi_32 and shm_32 will become permanently unavailable because the systems will be upgraded and moved to SLURM. The SLURM documentation will be appropriately updated as soon as this upgrade is completed. We will keep you up-to-date about the status of the cluster via this document.
