PETASCALE COMPUTING

Large scale parallel computing is a potential boon to the scientific interests of the geoscience communities and in particular oceanography. Over the next decade, computing systems will routinely attain peak speeds of one petaflop and more (1015 floating point operations per second) with memory capacities of order one petabyte (1015 bytes of information). This is at least an order of magnitude increase compared to the current generation of parallel machines (e.g., the IBM SP6 and Blue/Gene machines, see http://www.top500.org/ for current trends in supercomputing as well as the current ranking of the most powerful machines). An example of a peta-class system under development is the “Blue Waters” Project (http://www.ncsa.uiuc.edu/BlueWaters) being pursued by the National Center for Supercomputing Applications. Blue Waters aims to achieve sustained petaflop performance utilizing 106 computational cores and is projected to come online by 2011. By embracing petascale computational technology (recent developments in both hardware and software are described at http://www.image.ucar.edu/Workshops/TOY2008/focus2) early in its development phase oceanography will be in an advantageous position to advance its science and applications as even more powerful computational systems are developed.
