The EAR library https://doku.lrz.de/energy-aware-runtime-10746191.html has been set to ‘off’ by default on SuperMUC-NG Phase 1 due to spurious segfaults with MPI-Allreduce. A bugfix is under way and will be rolled out with the next release of EAR. Meanwhile you can use EAR explicitly with #SBATCH --ear=on in your batch script, if your code is not affected by the bug.
