Compile and run environment on Daint

The successful compilation and running of COSMO on Daint seems to be quite sensitive to some environment aspects and to the job specifications. Compiling and running in the environment described below worked for me (in February 2017). In case you experience troubles on Daint, please try to use this environment and job specifications. If it still doesn't work, just contact Katie Osterried or ask CSCS help for support.

Job specifications (runscript)

#!/bin/bash -l

#SBATCH --job-name="cosmo"
#SBATCH --ntasks=44
#SBATCH --output=job.out
#SBATCH --time=00:30:00
#SBATCH --constraint=gpu

srun -u -n 44 ./cosmo
Of course you have to adapt this runscript to your needs: number of tasks, job name, path, name of the executable. spacer
