Dear users of the Linux Cluster Systems at LRZ, Unfortunately, return of the MPP cluster to user operation (originally planned for November 11) as well as the start of operation of the new Ultraviolet Cluster segments (originally planned for early November) will be delayed. For both the MPP cluster and the UltraViolet systems, we are now targeting November 23 for return to user operation. This assumes that we do not run into further, presently unknown technical issues. Apart from the technical problems we have encountered both in moving the MPP cluster to its new location and in performing software integration of the SLURM queuing system with sgi's system software on the Ultraviolet, the presently very constrained LRZ staff resources have also contributed to the delays.
