Dear users of the visualization systems gvs1 and gvs2, Due to a major update of the system software, the visualization systems will be unavailable for user operation between March 26, 8:00 am and March 27, 6:00 pm. Please note that after the maintenance, the available software packages may require different startup and/or usage patterns than before. The documentation linked from http://www.lrz.de/ services/compute/visualisation/ will be updated on March 27 to reflect this; please read the relevant pages there to learn what exactly must be changed in your setups. SLURM instead of SGE will be used internally for submission of jobs. After the maintenance, four visualization systems gvs1-4 will be available instead of the two provided up to now. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/aktuell/ali4271/ Reinhold Bader
