Someone would have to write a GPU benchmark for that. My code is CPU-only.

I've uploaded the gnuplot script I used to generate the graphs here:
You will need to modify the script with your path to the simulation output file.

Good catch. There was a bug in the time measurement code in the
benchmark. Should be fixed now in the master branch.
