top500:roadrunner supercomputer retained the leadership   The other day took place, thirty-second, the conference SCO 2008, which was promulgated a new list of the most productive supercomputers to date. It must be said that the conference has become one of the most interesting and unpredictable, because for the first time in a long time for first place fought two systems from different manufacturers - already well known to the public IBM Roadrunner, the leader of the previous Top500, and a relative newcomer - upgraded Cray XT5 Jaguar.
victorious from this battle has more experienced IBM Roadrunner - productivity Cray XT5 Jaguar was 1, 059 petaflops in test annex Linpack. However, two computer monster showed almost identical results - performance leader, was 1, 105 petaflops, but if Cray XT5 Jaguar was ready in summer 2008, he became a winner, because at that time productivity Roadrunner was 1, 026 petaflops. Nevertheless, the design and assembly of complex structures such as computer productivity petaflopsa more than one - a tremendous achievement engineers Cray, so much so that Cray XT5 Jaguar is only the second computer that can overcome these bar. All other systems are lagging behind the two leaders so much that next year, 23 June 2009, distribution of powers in the Top500 is unlikely to change.
The third position went up supercomputer SGI Altix Pleiades, set by the Research Center of NASA. Performance computer is 0, 487 petaflops, more than half of the achievements of Jaguar and Roadrunner.
interesting that in the Cup of designers led by no means Cray, and not even IBM, a company HP - of the five systems represented 209 (41, 8%) manufactured by HP. IBM is in second place 186 computers, a Cray becomes bronze winner with 22 supercomputers. However, the latest upset no reason - just three of its hit list of the ten most powerful computers, in addition to the above-mentioned Cray XT5 Jaguar highest positions occupied Cray XT4 Franklin and Cray XT4 Jaguar (seventh and eighth place respectively).
is interesting to look at the statistics Supercomputing countries - the leader here, as indeed on the number of systems (291 machine) and their total output, is the United States. They should Britain, which accounted for forty-five supercomputers, and then just a little off from each other:France (26), Germany (24), Japan (18) and China (15). With regard to Russia, its territory functioning as soon as eight supercomputers.
