Requires NetCDF, MPI
Make sure that your compiler and mpif90 are in your path or edit the configure.wrf file and provide the full path
In the “WRFV3_BENCH” directory type
./configure
Pick an option that specifies dmpar (e.g. option “11” for icc)
Use basic nesting (“1”)
To compile WRF:
./compile em_real
To run the test case:
cd test/em_real mpirun -np <# procs> ./wrf.exe
Report the seconds per step reported by the following command when run in the same directory
grep "Timing for main" rsl.out.0000 | awk 'BEGIN{t=0;at=0;i=0;}{t=t+$9;i=i+1;}END{at=t/i;print "\nAverage Time: " at " sec/step over " i " time steps\n"}'
