Dear WRF users,<br>  <br>    I&#39;m a beginner to WRF and want to test its performance scaling on a HPC cluster. Installed it successfully with MPI support for parallel.<br><br>To check whether the compilation is successful or not, executed a sample test &#39;em_b_wave&#39; with run_hours=10. But it executed for a few seconds even though I had mentioned 10 hours. <br>
<br>I&#39;m don&#39;t know whether this successful or not.<br><br>The commands used are:<br><br>./ideal.exe<br><br>./wrf.exe<br><br>The generated output files are: <br><br>rsl.out.0000     - file attached<br>rsl.error.0000   - file attached<br>
