a) For technically knowledgable audience, you could demonstrate some
simple benchmarks codes.
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 (https://openfoam.com/) has some
demo setups that can give good motivation. FENICS
(https://fenicsproject.org/) and DEAL.II (https://www.dealii.org/) also
have some things. If Oil and Gas industry SpecFEM3D
(https://geodynamics.org/cig/software/specfem3d/). If computational
chemistry NWChem (http://www.nwchem-sw.org/index.php/Main_Page) 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
(https://en.wikipedia.org/wiki/Embarrassingly_parallel), ideally setup
so that upper management can execute it. One such application is Mitsuba
(https://www.mitsuba-renderer.org/), some measurements for Mitsuba on a
small 2 node setup can be found at
https://courses.cs.ut.ee/MTAT.08.037/2015_spring/uploads/Main/Martoja.pdf
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.

Yes, we have built a few of them. We have one here, one at AMSE, and
one that travels to schools in one of our traveling science trailers.

Hey Scott, I think I saw an exhibit like what you’re describing at
the AMSE when I was on a project in Oak Ridge. Was that it?

We still have Tiny Titan <https://tinytitan.github.io> even though
Titan is gone. It allows users to toggle processors on and off and
the display has a mode where the "water" is colored coded by the
processor, which has a corresponding light. You can see the frame
rate go up as you add processors and the motion becomes much more
fluid.

I recently inherited management of a cluster and my knowledge
is limited to a bit of Red Hat. I need to figure out a demo
for upper management graphically demonstrating the speed up of
running a parallel app on one x86 node versus multiple nodes
up to 36. They have dual Gold 6132 procs and Mellanox EDR
interconnect. Any suggestions would be appreciated.
