Better benchmarking for supercomputers

People today typically judge supercomputers in terms of their raw number-crunching power, for example by asking how many linear algebra problems they can solve in a second. But, the scientists argue, the lion´s share of challenging supercomputing problems in the 2010s requires quick and efficient processing of petabyte and exabyte-size data sets. And good number crunchers are sometimes bad exascale sifters.
