##Run## * Set LD_PRELOAD depending on the src code type (first command below for Fortran codes, the second for C/C++ codes):

    export LD_PRELOAD=$CRAY_MPICH2_DIR/lib/libfmpich.so:/apps/daint/darshan/2.2.9/gnu_482/lib/libdarshan.so:$LD_PRELOAD
    export                                   LD_PRELOAD=/apps/daint/darshan/2.2.9/gnu_482/lib/libdarshan.so:$LD_PRELOAD

copy test_letkf directory to $SCRATCH
copy exe from <LETKF_ROOT>/3dvar/build/LINUX64.gfortran45-debug/bin/var3d to $SCRATCH/<path_to_LETKF>/test_letkf/bin
modify run_job.bash (NPX, NPY, RUNDIR, INDIR, OUTDIR...)
type: ./run_job.bash
