Thank you for taking the time to write that up, Benson, we’ll take a look.

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.

Was that it?

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 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.
