Petaflop computing in the 21st century

Significant advance was fabricated in the aboriginal decade of the 21st aeon and it was apparent that the ability of a ample cardinal of baby processors can be acclimatized to accomplish aerial performance, e.g. as in Arrangement X's use of 1,100 Apple Ability Mac G5 computers bound accumulated in the summertime of 2003 to accretion 12.25 Teraflops.22

The ability of supercomputers connected to increase, but not badly so. The Cray C90 acclimated 500 application of ability in 1991, while by 2003 the ASCI Q acclimated 3,000 kW while actuality 2,000 times faster, accretion the achievement by watt 300 fold.23

In 2004 the Earth Simulator supercomputer congenital by NEC at the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) accomplished 131 teraflops, application 640 nodes, anniversary with eight proprietary agent processing chips.24

The IBM Blue Gene supercomputer architectonics begin boundless use in the aboriginal allotment of the 21st century, and 27 of the computers on the TOP500 account acclimated that architecture. The Blue Gene access is somewhat altered in that it trades processor acceleration for low ability burning so that a beyond cardinal of processors can be acclimated at air cooled temperatures. It can use over 60,000 processors, with 2048 processors "per rack", and connects them via a three-dimensional torus interconnect.25

Progress in China has been rapid, in that China placed 51st on the TOP500 account in June 2003, again 14th in November 2003 and 10th in June 2004 and again 5th during 2005, afore accepting the top atom in 2010 with the 2.5 petaflop Tianhe-I supercomputer.2627

In July 2011 the 8.1 petaflop Japanese K computer became the fastest in the apple application over 60,000 bartering scalar SPARC64 VIIIfx processors housed in over 600 cabinets. The actuality that K computer is over 60 times faster than the Earth Simulator, and that the Earth Simulator ranks as the 68th arrangement in the apple 7 years afterwards captivation the top atom demonstrates both the accelerated access in top achievement and the boundless advance of supercomputing technology worldwide.282930
