[Wrf-users] WRF-3.1: Qn about em_b_wave test

[Sangamesh B]

Dear WRF users,

    I'm a beginner to WRF and want to test its performance scaling on a HPC
cluster. Installed it successfully with MPI support for parallel.

To check whether the compilation is successful or not, executed a sample
test 'em_b_wave' with run_hours=10. But it executed for a few seconds even
though I had mentioned 10 hours.

I'm don't know whether this successful or not.

The commands used are:

./ideal.exe

./wrf.exe

The generated output files are:

rsl.out.0000     - file attached
rsl.error.0000   - file attached
wrfout_d01_0001-01-01_01:00:00

The procedure that I followed is correct or wrong?

If I have to run it for 10 hours, what parameters should I modify in
namelist.input?

Thank you
