Q&A: What Roadrunner's petaflop Top500 milestone is all about
The Top500 list of the world's most powerful supercomputers passed a milestone Wednesday with the first system to achieve peak performance of 1 petaflop, or one quadrillion floating point operations per second. Erich Strohmaier, a computer scientist at Lawrence Berkeley National Laboratory, was one of the founding editors of the Top500 list back in 1993. He talked with IDG News Service about the performance gains the list has seen, the quad-core processors that are coming to dominate it and mistakes that can creep in when the list is put together.
