Dear users of SuperMIG, due to a problem with our NAT Gateway the user filesystems are not accessible on the compute nodes. This causes submitted jobs to be put on HOLD by the LoadLeveler batch system. The login nodes are not affected by the problem. We are working on the problem and will update this ALI as soon as the problems are fixed. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/supermuc/aktuell/ali4262/ Hans-Georg Kleinhenz
