When I talk about hpc, I don't talk about a script in Matlab. I talk about the work you do on supercomputers, real computing intensive jobs that takes weeks or months on hundreds or thousands of processors. I guess you don't find benchmarks simply because no one uses windows, same reason you probably don't find a fiat panda in the Nürburgring rankings.
K. Everything I've done is basically translating a Matlab script to Python using numpy or tensorflow or something. So we'd go from Matlab taking hours to Python taking minutes. The biggest project was a Monte Carlo simulation of signals produced from explosions (looking for seismographic impact) that takes something like 45 min per run when run on our cloud infra.
So something a little more interesting than plotting an FFT if overlaid signals, but still on the simpler end of the spectrum.
We're nowhere near the point where tuning the OS is interesting, we just use Linux because it's convenient. I wonder how much of the HPC crowd has a similar perspective, at least until you get to the higher end where tuning the OS becomes important.
You don't really need to tune the operating system, you just need a good one. The hpc crowd has a pretty unique perspective. You won't find anyone doing any real hpc on windows, not even Microsoft
