Top fastest supercomputers ranking published twice a year. The leader of the last two editions of the Japanese remained K Computer, whose performance is 10.51 petaflops. But now the title of king of supercomputers proudly wears the American system of IBM Sequoia, which has managed to overcome the barrier of 16.32 petaflops.
About three leaders, we have already mentioned . Now published a complete list of TOP500. It is interesting to note the appearance in the top ten of several large European systems, in particular, SuperMUC (IBM iDataplex), which is the leader in Europe and fourth in the world. This supercomputer is installed at the German Supercomputer Center (Leibniz-Rechenzentrum). Seventh position in the world took an Italian Supercomputer IBM BlueGene / Q, and the eighth – German JuQUEEN BlueGene / Q. Four of the ten fastest cars belong to the family BlueGene / Q. Among the European system distinguished French Bullx B510, which finished in ninth place. It was designed by Bull SA, includes a processor Xeon E5-2680 with a frequency of 2.7 GHz, 308 736 GB of memory, uses the interconnect Infiniband QDR. The operating system acts as bullx SUperComputer Suite AE2.1.
The aggregate performance of all systems in the list has increased from 74.2 to 123.4 petaflops. Moreover, 20 supercomputers broke the petaflop barrier of 1. 74.4% of all systems use processors Intel, which is worse last year. The number of systems based on AMD has remained unchanged, while the share of IBM Power rose to 11.6%. 58 supercomputers are using accelerators and coprocessors, 53 of which are produced NVIDIA. The two chips are used Cell, two – Radeon, and one – the technology Intel MIC.
As regards the distribution by region, the U.S. remains the leader, although their number decreased from 263 supercomputers to 253. The share of Europe accounts for 107 systems (in the last edition – 103). Asia is still ahead of Europe, and increased the number of supercomputers from 118 to 121.
