Changes to this message: Update Dear users of the Cluster and visualization systems at LRZ, After the maintenance and upgrade to SLES11, the systems 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. MS-Windows users have to read it carefully, because of substantial changes. Before logging in to gvs3 or gvs4, you may need to remove an obsolete ssh key from your $HOME/.ssh/known_hosts file. Update: The servers gvs1 and gvs2 are not available at the moment due to a technical defect, which is being investigated. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/aktuell/ali4280/ Reinhold Bader
