Oh, not again! There are serious apples vs. oranges issues in the comparison to the level making it completely irrelevant. They compare optimized compilations of one compiler with no-opt compilations of another compiler. They compare openmp builds of one compiler with non-openmp builds of another. The build and run logs or at least details are not provided, so people around trying to reproduce the result get completely different figures. See for example the comments to the article itself. http://www.phoronix.com/forums/showthread.php?t=15534&page=2 Alexander
