<p>Hi All, </p>
<p><br>
</p>
<p>I am running WRF on a ~6km resolution, <span style="font-size:10pt">91 x 121 domain in the eastern United States. I am using an adaptive time step which makes it mostly 72 sec increments. </span><span style="font-size:10pt">There are 34 vertical levels. I
use 4 x 12 cores on a Intel Xeon x5650 CPUs machine. </span><span style="font-size:10pt">The throughput is about 1.2 hour wall time per 24 hours model time. </span></p>
<p><span style="font-size:10pt"></span></p>
<p><span style="font-size:10pt"><br>
</span></p>
<p><span style="font-size:10pt">Is this a reasonable speed? I found some information here (<a href="http://www.ecmwf.int/sites/default/files/elibrary/2014/13662-performance-analysis-operational-implementaion-wrf.pdf" target="_blank">http://www.ecmwf.int/sites/<wbr>default/files/elibrary/2014/<wbr>13662-performance-analysis-<wbr>operational-implementaion-wrf.<wbr>pdf</a>)
and after considering the domain difference, my run still seems a touch slow. And i</span><span style="font-size:10pt">s there anyway I could figure how to make the model run faster?</span></p>
<p><span style="font-size:10pt"><br>
</span></p>
<p><span style="font-size:10pt">Thank you, </span></p><span class="HOEnZb"><font color="#888888">
