"inspired" == blatent ripoff to get around the reporting rules of LMbench. I had pretty harsh words with Jon, that paper should never have been published, he ripped off the benchmarks and published some of the results without all of them. You'll note that Eros is pretty dead, nothing came of it. It was an academic thing in search of a problem and Jon had to cheat to make it look good. It's not a good look on him, color me very disappointed but it isn't the first time some pointy headed PhD dude claimed a bunch of stuff that wasn't quite true.
