titleECMWF Cray HPC

When running on the ECMWF Cray XC40 the following changes need to be made:

  • In $OIFS_HOME/t21test/job.sh and t21test_xios_t255ac/setup-exp.sh include the line:  export  export OIFS_RUNCMD="aprun -n $NPROC -d $NTHREADS -ss $MASTER"This variable has to be modified again when you want to use XIOS, I suggest to set it up outside the script, either at the command line during an interactive session or in a submit script (see t21test_xios_t255ac/platform/ecmwf-cca.job.tmpl and t21test_xios_t255ac/platform/ecmwf-cca.job+xios.tmpl).

  • In $OIFS_HOME/t21test_xios_t255ac/platform/ copy file oifs-config.ecmwf-cca.sh to oifs-config.me.sh, open the latter file in an editor and change the variable settings and paths according to your environment. In $OIFS_HOME/t21test_xois_t255ac/setup-exp.sh edit the line:  platform=me

...

Note: assigning default value for $MASTER in setup-exp.sh does not seem to work ?  In the calls below, '-x' expects a  full path. If you want to use the default, just do not use that option. See: ./setup-exp.sh -h

./setup-exp.sh -n 12 -t 2 -x /perm/rd/damk/oifs/openifs-ac/make/cce-opt/oifs/bin/master.exe
