<p>Students, Classroom Educators (Professors), and Open-Source
Contributors might be able to get a free license for some Intel
tools:</p>

</p>
<p>For WIEN2k, I believe commercial researchers have to buy a
commercial license. Professors doing research are paid a salary
and student researchers are paid a stipend or are working on a
funded research project typically, such that they usually have to
buy an academic license:</p>
<a class="moz-txt-link-freetext" href="https://software.intel.com/en-us/articles/non-commercial-software-faq">https://software.intel.com/en-us/articles/non-commercial-software-faq</a><br>
<a class="moz-txt-link-freetext" href="https://software.intel.com/en-us/articles/academic-pricing">https://software.intel.com/en-us/articles/academic-pricing</a><br>
<br>
The old non-commerical license that was less restrictive on who
could use it or what it could be used for was discontinued:<br>
<br>

<p>For WIEN2k 17.1, if you use a ifort/mkl version older than update
2 of the 2013 composer xe, you need to patch the code to use the
-Dold_scalapack switch:</p>
<p><a class="moz-txt-link-freetext" href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16487.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16487.html</a><br>
</p>
<p>However, it is recommend to use a ifort/mkl version newer than
that, which uses the new pzheevr function. This is because there
were cases were the old Scalapack diagonalization failed:</p>
<p><a class="moz-txt-link-freetext" href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16484.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16484.html</a><br>
</p>
<p>You probably do NOT want to use the 16.0.3.210 version due to the
serious bug that it has:</p>
<p><a class="moz-txt-link-freetext" href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16520.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16520.html</a><br>
</p>
<p>Some, or perhaps all, of the 2016 and 2017 versions are known to
be problematic with large arrays and using -assume nobuffered_io
may help resolve this:</p>
<p><a class="moz-txt-link-freetext" href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16232.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16232.html</a><br>
</p>
<p>There are known file IO problems with 2018, but there may be
fixes in the mailings list for that:<br>
</p>
<p><a class="moz-txt-link-freetext" href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16589.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg16589.html</a><br>
</p>
<p>Depending on your Linux operating system version, you might want
to check the Intel Release Notes to determine which version has
matching support with the ifort/mkl version that you are using:</p>
<p><a class="moz-txt-link-freetext" href="https://software.intel.com/en-us/articles/intel-parallel-studio-xe-release-notes-and-new-features">https://software.intel.com/en-us/articles/intel-parallel-studio-xe-release-notes-and-new-features</a><br>
</p>
For example, the 2018 update 1 version of ifort/mkl has "4.3
Operating System Requirements":<br>
<br>
Debian* 8, 9<br>
Fedora* 25, 26<br>
Red Hat Enterprise Linux* 6, 7 (equivalent CentOS versions
supported, but not separately tested)<br>
SUSE Linux Enterprise Server* 11, 12<br>
Ubuntu* 14.04, 16.04, 17.04<br>
macOS* 10.12, 10.13<br>
<br>
Sorry, I currently don't know which of the 2016/2017/2018 ifort/mkl
versions are more stable with WIEN2k. So you would have to do your
own testing.<br>

Estimado Luis,<br>
You need a recent compiler for the WIEN2k 17.1<br>
As researcher you can get a free licence<br>
