Software Requirements

• Fortran 90/95 and C compiler

• MPI or OpenMP libraries

• netCDF4 library linked with HDF5 and zip libraries and extended by the Fortran netCDF package (The netCDF4 package comes with the programs ncdump and nccopy)

• UNIX utilities: make, ksh, uname, sed, awk, wget, etc.

• For post-processing: Climate Data Operators (CDO) and netCDF Operators (NCO)

• An ICON binary

The starter package is written for the HRLE–3 Mistral at DKRZ. Additional changes need to be applied on other machines. On the Mistral the Simple Linux Utility for Resource Management SLURM ist installed.
On mistral please use OPENMPI by setting

module load intel/17.0.2
module load openmpi/2.0.2p1_hpcx-intel14

export OMPI_MCA_pml=cm
export OMPI_MCA_mtl=mxm
export MCM_RDMA_PORTS=mlx5_0:1

...

this results in a much faster compilation. Replace N by the number of requested processors.

Run the test examples

There are two tests, one for testing CCLM with GCM or reanalysis data as initial and boundary conditions (${SPDIR}/chain/gcm2cclm/sp001) and one for testing CCLM with coarse grid CCLM data as initial and boundary conditions (${SPDIR}/chain/cclm2cclm/sp002). Actually sp001 creates the necessary input data for sp002.

Before you start the experiment look for the following environment variables in the job_settings of sp001 and sp002 file and adopt them to your needs.

PROJECT_ACCOUNT=  # your project account
EMAIL_ADDRESS=    # your email address if you want to get information when your job crashes or finishes
