They are used to do large-scale high-resolution analysis or simulation of complex systems in the physical world. The codes typically run on the bare metal with careful control of resource affinity, often C++ these days.

They aren't just used for global-scale geophysical processes like weather and climate or complex physics simulations. For example, oil companies rent time to analytically reconstruct the 3-dimensional structure of what's underneath the surface of the Earth from seismic recordings.

What do you mean bare metal? Because all of the big DOE computers are running Linux. Users will probably use hardware specific libraries (like CUDA/ROCm) and occasionally write some hardware specific asm, but none of the big computers are running without a POSIX OS.

I think they mean not in a VM, and instead using some job manager like slurm or condor. Typically users wouldn't have superuser privligles precluding the use of thigns like docker, which is why Singularity exists.
