Dear users of the Linux Cluster systems, due to the second stage of necessary works on the electrical infrastructure, a subset of the HPC cluster systems at LRZ will be unavailable for user operation on Oct 28, starting at 8:00 am. The systems impacted are: * Serial partition of the Linux cluster * Myrinet partition of the Linux cluster * some housed cluster partitions We have taken steps to assure that the operation of the network can continue without interruption; therefore we expect that all other cluster parts remain available for user operation. We ll keep you updated about the status of all cluster systems via this document. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/aktuell/ali4682/ Reinhold Bader
