Dear users of the Linux Cluster systems at LRZ, unfortunately the serial part of the cluster is not yet available for user operation; the OS upgrade procedure has run into unforeseen problems. We hope to be online again within this week. Please note that * the login nodes have new names lxlogin1, lxlogin2, lxlogin3. The old names (lx64ia2, lx64ia3) will continue to be available, however the "lrz-muenchen.de" in the fully qualified host names must be replaced by "lrz.de" * SGE will not be available any more for job processing; it has been replaced by the SLURM scheduler. Please consult the SLURM documentation at http://www.lrz.de/services/compute/linux-cluster/ batch_serial/ for information on the required changes to your script. * It may be necessary to recompile binary executables because the new operating environment has a newer and potentially incompatible C library "glibc".
