<p>a) For technically knowledgable audience, you could demonstrate
some simple benchmarks codes.</p>
<p>b) For a more general audience, you might also look for some
parallel open source applications that are specific to the domain
of interest. For example for engineering, OpenFOAM
(<a class="moz-txt-link-freetext" href="https://openfoam.com/">https://openfoam.com/</a>) has some demo setups that can give good
motivation. FENICS (<a class="moz-txt-link-freetext" href="https://fenicsproject.org/">https://fenicsproject.org/</a>) and DEAL.II
(<a class="moz-txt-link-freetext" href="https://www.dealii.org/">https://www.dealii.org/</a>) also have some things. If Oil and Gas
industry SpecFEM3D
(<a class="moz-txt-link-freetext" href="https://geodynamics.org/cig/software/specfem3d/">https://geodynamics.org/cig/software/specfem3d/</a>). If
computational chemistry NWChem
(<a class="moz-txt-link-freetext" href="http://www.nwchem-sw.org/index.php/Main_Page">http://www.nwchem-sw.org/index.php/Main_Page</a>) might be nice.
There are of course many other codes as well. If the cluster is
mostly used as a task farm to run many single node jobs rather
than for a large parallel application, some embarrassingly
parallel task is fine
(<a class="moz-txt-link-freetext" href="https://en.wikipedia.org/wiki/Embarrassingly_parallel">https://en.wikipedia.org/wiki/Embarrassingly_parallel</a>), ideally
setup so that upper management can execute it. One such
application is Mitsuba (<a class="moz-txt-link-freetext" href="https://www.mitsuba-renderer.org/">https://www.mitsuba-renderer.org/</a>), some
measurements for Mitsuba on a small 2 node setup can be found at
<a class="moz-txt-link-freetext" href="https://courses.cs.ut.ee/MTAT.08.037/2015_spring/uploads/Main/Martoja.pdf">https://courses.cs.ut.ee/MTAT.08.037/2015_spring/uploads/Main/Martoja.pdf</a><br>
</p>
<p>Probably most useful is to find out users of the cluster and have
one or two of them explain how you have/will help improve company
profitability by making their workflow more effective. <br>
