I am supposed to be writing some more stuff for my PhD thesis, but this feels like a more legitimate way to procrastinate than others…
I have plotted the performance of a model of a multi-core processor system and, because it was something to do, applied a Fourier Transform to the data (the black plots in first chart):
So, my question is, what does the second chart mean? If it means anything of course.
I get that the real component is plotted on the x-axis and the imaginary component on the y-axis, but is there any information conveyed in the chart?
