MOSCOW, Sept. 23 -- For the 5th time in a row T-Platforms, the major Russian supercomputer company, leads the rating in regard to the number of systems on the list.
The Research Computing Center of Lomonosov Moscow State University and the RAS Joint Supercomputer Center have released the 11th edition of the Top50 list of the most powerful computers of Russia and the CIS. The new edition was announced on September 22 at the all-Russia scientific conference "Scientific service on the Internet: scalability, parallelism, efficiency". For the 5th time in a row T-Platforms leads the rating in regard to the number of systems on the list (16 out of 50).
The top twenty of the list has remained unchanged. Like in the previous edition, the list is topped by MVS-100K supercomputer installed at the RAS Joint Supercomputer Center with Linpack-measured performance of 71,28 Tflops. The second position is occupied by SKIF MSU Chebyshev supercomputer based on blade systems developed by T-Platforms company. The supercomputer is installed at the Research Computing Center of Lomonosov Moscow State University and has Linpack-measured performance of 47,3 Tflops (computing efficiency - 78,9 percent). Since deployment in 2008 the supercomputer capacities have been fully loaded with computational jobs.
The 11th edition of the list has shown the minimal performance growth rate since the rating foundation. The total actual performance of the systems has grown from 382.6 Tflops to 387.1 Tflops within half year. The rating has updated by 10 percent - 5 systems out of 50 are new or upgraded.
Amongst the upgraded systems is a supercomputer with real performance of 1,505 Tflops installed at T-Platforms Cluster Solutions Center (CSC). It has gone 7 positions up compared to the previous rating and occupied the 39th position of the new list. This supercomputer is the only system in Russia that consists completely of nodes based on 9-core PowerXCell 8i processors; the compute nodes of the supercomputer were designed by T-Platforms.
The number of supercomputers with actual performance exceeding 1Tflop has grown from 47 to 49 in the new edition. The minimum threshold for entry into the Top50 list now amounts to 978Gflops of Linpack-measured performance (924,4Gflops in the previous edition).
The number of systems used in science and education has grown from 30 to 31 systems, and the number of supercomputers used for research has decreased from 10 to 9.
The shares of processor vendors have remained unchanged in the 11th edition of the rating: Intel - 37 systems, AMD - 7, IBM - 5 and Hewlett Packard - 1 system.
Supercomputers.ru is a joint project of Lomonosov MSU Research Computing Center and the RAS Joint Supercomputer Center. The Top 50 most powerful supercomputers rating has been published on this portal since May, 2004. The rating includes 50 most powerful (as tested by Linpack) supercomputers installed in the CIS. It doesn't include experimental and temporary systems and is updated twice a year. To avoid intentional system data overvaluation, Supercomputers.ru employees check the real supercomputers parameters on a sample basis.
The Xeon Phi coprocessor might be the new kid on the high performance block, but out of all first-rate kickers of the Intel tires, the Texas Advanced Computing Center (TACC) got the first real jab with its new top ten Stampede system.We talk with the center's Karl Schultz about the challenges of programming for Phi--but more specifically, the optimization...
Although Horst Simon was named Deputy Director of Lawrence Berkeley National Laboratory, he maintains his strong ties to the scientific computing community as an editor of the TOP500 list and as an invited speaker at conferences.
Supercomputing veteran, Bo Ewald, has been neck-deep in bleeding edge system development since his twelve-year stint at Cray Research back in the mid-1980s, which was followed by his tenure at large organizations like SGI and startups, including Scale Eight Corporation and Linux Networx. He has put his weight behind quantum company....

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
