Upd:Linux Cluster: UV returned to operation
by LRZ aktuell Feb. 8, 2013

Feb. 8, 2013

Changes to this message: Update Update (Feb 8, 15:00): The Ultraviolet systems hav been returned to user operation. Please see below what you need to do as a consequence of the configuration changes. ----------------------------------------------------------------------- Recent configuration changes: * The default MPI environment on the MPP cluster was changed from Parastation MPI to Intel MPI. However, the mpi.parastation module will remain available for legacy use until the end of 2013. On the sgi ICE and UV systems, the sgi MPI (mpi.mpt) will remain default. We strongly recommend that you recompile your applications with Intel MPI. If you insist on still running Parastation MPI binaries, you need to add the following lines to your SLURM job scripts: module unload mpi.intel module load mpi.parastation/5.0/intel * The 8-way Myrinet Cluster has been retired from parallel processing, and the nodes were added to the serial processing pool. This implies that the partition "myri_std" in the SLURM cell "myri" is now unavailable. * For the serial queues, SLURM fair share scheduling was introduced. For the parallel queues, a combination of fair share scheduling and favoring large jobs is now active. This is to prevent a single user from monopolizing cluster segments for long times if there are many jobs in the queue. * New storage systems have been introduced for the WORK (==PROJECT) and SCRATCH file systems. Please note that LRZ has only migrated WORK data to the new file system; data in SCRATCH have not been migrated. However the old SCRATCH file system will remain available as a separate mount in read-only mode on the login nodes until the end of March, 2013. Migration of data can then be done via commands like cd $SCRATCH_LEGACY cp -a <my_scratch_subdirectory> $SCRATCH The environment variable $SCRATCH_LEGACY will remain defined and point to the legacy scratch area until end of March, 2013.
