This seems to have fixed my problems for shared-memory parallel WRF 3.1 (smpar) on Linux. <br><br>I'm using RedHat with 8 quad-core Intel Xeon 5335 processors and Intel compilers v. 10.x<br><br>I had been getting seg faults at runtime. I got the fixed files from:<br>
<br><a href="http://www.mmm.ucar.edu/wrf/WG2/ifort_mac/README.txt">http://www.mmm.ucar.edu/wrf/WG2/ifort_mac/README.txt</a><br><br>as per<br><br><a href="http://mailman.ucar.edu/pipermail/wrf-users/2009/001257.html">http://mailman.ucar.edu/pipermail/wrf-users/2009/001257.html</a><br>
<br>I cleaned, reconfigured and recompiled with the new files. Because I compiled with the linux smpar option, I don't think my configure.wrf file was any different - certainly no changes to ldflags_local, (that would only have changed on Mac OS). I had to do <br>
<pre> setenv KMP_STACKSIZE 100M</pre><br> and after that things ran with no problems, in parallel.<br><br>Thank you!<br><br>NB: the speedup for my general test scenario was about 4x now that my system is using 8 processors instead of just one (32 cores vs 4). <br>
