Yes, but it pegs the processor(s) when it's running, so there's the potential for increased energy consumption and faster hardware burnout. Also it seems like it would be a sensible policy to have systems go into low power/sleep mode while unused rather than doing FFTs all night, though the article didn't offer enough details to determine if this was an issue or not.
