Is it possible to achieve a teraflop/s on a chip? From high performance algorithms to architectures

The forumnists address the question of high density computations on a single chip. The surface of a chip offers an ideal medium not only to store information or to process data, but also to execute computations. The 1 Giga floating point operations per second per chip mark has been achieved, we are now moving towards the teraflop mark. How is this going to happen, what are the limitations, what are the opportunities-those are central questions
