Dear users of the SuperMUC Petaflop system and the HPC Clusters at LRZ, the presently used default versions of the Intel development software stack (compilers, tools, libraries and Intel MPI) will be changed over to more recent releases on the afternoon of September 23, 2013. As a result, it may in some cases become necessary to either recompile your application under the new environment, or to manually switch (via the module command) over to the previously used software releases which will remain available for some time. Furthermore, a number of obsolete software packages or versions will be removed, and the default versions of some packages will be updated to more recent releases. If you have difficulties using the new releases, please inform us as soon as possible via the service desk. ----------------------------------------------------------------------- The following table indicates the most relevant provided fallback modules: Updated module version Fallback version fortran/intel/13.1 fortran/intel/12.1 ccomp/intel/13.1 ccomp/intel/12.1 mpi.intel/4.1 (uses 4.1.1) mpi.intel/4.1.0 This information is also available on our web server http://www.lrz-muenchen.de/services/compute/aktuell/ali4662/ Reinhold Bader
