Euler¶

Euler is ETH Zurich's central high-performance computing (HPC) cluster, providing computational resources for research across all disciplines.

Access¶

Groups at IAC have shares for storage and CPU via the Euler Climate group. As a group member, you should have an existing account and access to Euler. If this is not the case, contact your group leader or Urs Beyerle.

Software Stack¶

Euler provides a software stack via the module command:

module load stack openmpi
module list
# Currently Loaded Modules:
#  1) gcc/12.2.0   2) stack/2025-06   3) openmpi/4.1.7

Afterwards, one can load specific software such as:

module load cdo nco ncview netcdf-c
module list
# Currently Loaded Modules:
#  1) gcc/12.2.0   2) stack/2025-06   3) openmpi/4.1.7   4) cdo/2.4.4   5) nco/5.2.4   6) ncview/2.1.9   7) netcdf-c/4.9.2

With that, one has access to the most commonly used tools for climate applications:

which cdo ncdump ncview ncrcat
