Changes to this message: Update Status update Jan 17 16:15 Both ICE and UV systems are now available again. However, running Intel MPI programs on the UV does not work in many cases; this also may impact applications installed by LRZ. If you obey all of the following rules when using Intel MPI things may work: * Use version 4.1 of Intel MPI (module load mpi.intel/4.1) * Use 64 tasks or less We will continue investigation of this problem but cannot promise a quick resolution. Programs using sgi MPT are (to our present knowledge) not impacted by this problem. Please also note that the update work on the ICE was only partially successful; a separate maintenance window will be announced in a few weeks for completion of the updates. ----------------------------------------------------------------------- Dear users of the Linux-Cluster systems at LRZ, due to a necessary operating system update the ICE and UV systems will be unavailable for user operation for a few days. The maintenance starts on Monday, Jan 14 at 8:00. We expect the systems to be returned to user operation during the afternoon of Jan 16. Further changes that apply post-maintenance will be announced via this document.
