Hi,<br><br>According to your output files, your run was successful and evolving the test case for 10h. (this is 10h in model time, not in wall time. It could well be ok, that it only takes a few seconds to finish that kind of run.)<br>
<br>In your output files (i.e. rsl.error.0000, ...), you find lines like <br><br>Timing for main: time 0001-01-01_10:50:00 on domain 1: 1.27500 elapsed seconds.<br><br>that show you the model time, and the wall time seconds it took to compute that iteration.<br>

Dear WRF users,<br> <br> 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.<br><br>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. <br>
<br>I'm don'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>
