<p class="bodytext">Yellowstone is NCAR's high-performance supercomputer, used for research by NCAR, UCAR, and university users. The latest version of WRFDA (version 3.8) can be compiled and run using Yellowstone's default module (Intel 12.1.5), but some users may want to use different compilers. Here is a list of tested compilers, as well as some configurations which are known not to work:</p>

<p class="pagetitle">Older versions</p>
<p class="bodytext">In November 2012, NCAR officially brought the new supercomputer "Yellowstone" online, replacing the old <a href="https://www.cisl.ucar.edu/computers/gallery/ibm/bluefire.jsp">Bluefire machine</a>. Due to the architecture differences between Yellowstone (a Linux architecture with Intel, PGI, GNU, and Pathscale compilers) and Bluefire (an AIX architecture with xl compilers), there are some older versions of WRFDA that do not work as anticipated on Yellowstone. This page details the various older WRFDA versions that are known to work on Yellowstone, and the compilers with which they can be used, in addition to providing fixes for some known problems.</p>
<p class="bodytext">Not all configurations have been tested, so if you encounter a problem running a version of WRFDA which is not listed here as a known problem, please contact <a href="wrfhelp.html">wrfhelp</a>.</p>

<h1>Versions with major problems</h1>

<!-- <p class="bodytext"><b>NOTE: We <em>HIGHLY</em> recommend using the latest version of WRFDA on Yellowstone. However, if you must use an older version, you can try the fixes below.</b></p>-->

<tr>
<th colspan="2" style="text-align: center;">Intel (ifort, icc)</th></tr>

<td rowspan="2";>WRFDA V3.3</td>
<td><b>Problem: </b> "Configure" script reports a compiler error and may remove files from the top directory.</td></tr>
<td><b>Solution: </b> If the top directory, including the configuration scripts, has been blanked, you will need to unpack the code again from your original "WRFDAV3.3.TAR.gz" file. If you do not have this file you must <a href="download/get_source.html">re-download the WRFDA package</a>.<br>
Once this step is completed, download the <a href="http://www2.mmm.ucar.edu/wrf/src/fix/configure_fix.tar">configure_fix.tar</a> file, and unpack it in the top WRFDA directory. This fix contains new "configure" script and a new "arch/configure_new.defaults" file. You should now be able to configure and compile WRFDA normally.</td></tr>
