+ - Petaflop, exaflop and zettaflop Computing

Submitted by

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."
