Changes to this message: Prolongation of maintenance Update 2 (Jan 31 17:50): Internal testing unfortunately has revealed a number of problems that prevent us from returning the SuperMUC system to user operation. We intend to provide daily updates on the status of the system. ----------------------------------------------------------------------- Update (Jan 30 afternoon): In order to check additional hardware and firmware modifications that were done to improve the stability of the system (see also http://www.lrz.de/services/compute/supermuc/aktuell/ ali4512/, as well as dedicated operation for a project that requires short-term use of the complete machine, user operation of the system is delayed to the afternoon of January 31. ----------------------------------------------------------------------- Dear users of the SuperMUC petascale system at LRZ, Due to a combined hard- and software maintenance, SuperMUC will be unavailable for user operation between January 28, 8:00 and the afternoon of January 31. Jobs still running at the beginning of the maintenance will be cancelled. The following changes are introduced by this maintenance: * Access to the PRACE network will become available to PRACE users, * LoadLeveler mail notification will be activated, * Licence servers will be accessible from the compute nodes, * The Infiniband software stack will be updated to a newer release, * Some presently missing packages will become available on the compute nodes (e.g., you can remove the workaround for a missing libnuma.so) This information is also available on our web server http://www.lrz-muenchen.de/services/compute/supermuc/aktuell/ali4502/ Reinhold Bader
