Hi<div><br></div><div>Thanks for help.</div><div>Today I test wrf3.3 with 224 cores. It goes well. But when I increase cores to 1120, wrf.exe didn't integrate after 6 hours and it also didn't stop or return any error massage.</div>
<div>The rsl.out.0000 show that wrf.exe stop at deal with domain2. Last 20 lines of

Is there a limit of core number that WRF could use? I plan test WRF with 2048 cores or more next week. Could WRF run with such huge number?<br>
Thanks a lot.<br>
