BIG BLACK BOX: We Are On The Verge Of Building An Exascale Computer. But What Does That Mean?

New Scientist -- The roadmap for exascale hardware is fairly well laid out. Software and algorithms to run across potentially billions of cores may be trickier. “Every generation of supercomputers leaves some users behind,” says William Gropp, CS professor and director of the National Center for Supercomputing Applications. “That’s been a constant problem and I think we’re going to see it again.” (behind paywall)
