A Chinese mainframe} has taken the highest spot in a very list of the quickest machines on the earth – demonstrating nearly double the performance of the USA computer that antecedently command the title.
The Tianhe-2, or opaque Way-2, a mainframe computer developed by China's National University of Defense Technology, is that the most powerful pc within the world per the TOP500 list.
It takes the highest spot from Titan, a Cray XK7 system put in at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory, that drops to variety 2 within the latest list.
The Milky Way two recorded thirty three.86 petaflops on the Linpack benchmark, compared to the Titan's score of seventeen.59 petaflops.
The two high machines suppose terribly totally different architectures. Milky Way two has sixteen,000 nodes, every with 2 Intel Xeon IvyBridge processors and 3 Xeon alphabetic character processors, for a combined total of three,120,000 computing cores.
Meanwhile the Titan depends on 261,632 NVIDIA Tesla K20x GPU accelerator cores. Titan is one amongst the foremost energy economical systems on the list, overwhelming a complete of eight.21 MW and delivering two,143 Mflops per Watt.
Milky Way-2 are going to be deployed at the National mainframe computer Center in Guangzho, China by the tip of the year.
Sequoia, AN IBM BlueGene/Q system put in at DOE's Lawrence suffragist National Laboratory, additionally born one position and is currently at variety 3 within the list. redwood was initial delivered in 2011 and has achieved seventeen.17 petaflops on the Linpack benchmark victimisation one,572,864 cores.
Sequoia is additionally one amongst the foremost energy economical systems on the list, overwhelming a complete of seven.84 MW and delivering two,031.6 Mflops per Watt.
Fujitsu's "K computer" put in at the RIKEN Advanced Institute for machine Science (AICS) in Kobe, Japan, is that the variety four system, with a performance of ten.51 petaflops on the Linpack benchmark victimisation 705,024 SPARC64 process cores.
A second BlueGene/Q system, Mira, put in at military operation National Laboratory is at variety 5 with eight.59 petaflops on the Linpack benchmark victimisation 786,432 cores.
Rounding out the highest ten ar the upgraded Stampede at the TX Advanced Computing Center of the University of TX, Austin; JUQUEEN at the Forschungszentrum Juelich in European country - the foremost powerful system in Europe; AN IBM BlueGene/Q system at Lawrence suffragist National Laboratory; SuperMUC, AN IBM iDataplex system put in at Gottfried Wilhelm Leibnitz Rechenzentrum in Germany; and Tianhe-1A at the National Supercomputing Center in urban center, China.
A total of fifty four systems on the list ar victimisation accelerator/co-processor technology, down from sixty two within the last list in Nov 2012. ixl of those use NVIDIA chips, 3 use ATI Radeon, and eleven systems use Intel Xeon alphabetic character.
Total combined performance of all five hundred systems has mature to 223 petaflops, compared to 162 petaflops six months agone and 123 petaflops one year agone.
The results of the list were discovered at the International Supercomputing Conference in metropolis in European country yesterday.
