Submission + - Petaflop, exaflop and zettaflop Computing

nanotrends writes: "A look at several papers on the limits of computing and paths to getting to a zettaflop of computing power.

1 Zettaflop = a billion teraflops = a million petaflops = a thousand exaflops.

This is a 2006 paper that examines paths to getting to a zettaflop

The paper looks at conventional silicon approaches to a zettaflop system. (such a sytem would need an exabyte of memory at a minimum). They look at Quantum dot Cellular automata (QCA) zettaflop systems. They examine reversible computing and suggest 5 year, 2010-2015, and 2015-2025 plans.

There is some examination of Japan's plans for 10 petaflops through exaflop systems and what would be applications that would need that much computing power."

Any given program will expand to fill available memory.
