Dear users of SuperMIG, the power cut-off tests announced in http://www.lrz.de/aktuell/ali4261/ will also cause an interruption of service for SuperMIG, since the NAS filesystems will not be available. Access to SuperMIG will not be possible from March 25th, 17:00 until March 26th, 18:00. The downtime will also be used to perform the regular sytem maintenance. We apologize for the inconvenience caused by this interrupt and will inform you through this ALI when the system is back in production. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/supermuc/aktuell/ali4294/ Hans-Georg Kleinhenz
