Dear users of the Cluster and visualization systems at LRZ, After the maintenance and upgrade to SLES11, the systems gvs1, gvs3 and gvs4 are now available for use again. Please consult the documentation at http://www.lrz.de/services/compute/visualisation/, especially the Quickstart Guide, for updated usage instructions. gvs2 has not been returned to user operation due to a technical defect, which is being investigated. Before logging in to gvs1, you may need to remove an obsolete ssh key from your $HOME/.ssh/known_hosts file. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/aktuell/ali4280/ Reinhold Bader
