We proudly present SPbPU supercomputer center, one of the most innovative HPC centers in Russia, at ISC 15 international conference. First of all we would like to point on abilities of our scientists in various subject areas that require high performance computing. We would also like to know more about the experience of our foreign colleagues in this field," said Vladislav Sinepol, Director of SPbPU supercomputer center. New Polytechnic RSC Tornado cluster system with direct liquid cooling has the peak performance of 829 Teraflops. It is the 3 rd in Russian Top50 list of the most powerful supercomputers with 658 Teraflops performance at LINPACK test as well as it is ranked by Top500 and Green500 global ratings. It is the first project in Russia and CIS based on new Intel Xeon E v3 server processors. Polytechnic RSC Tornado includes 712 dual-processor nodes containing 1424 high-performance Intel Xeon E v3 server processors (14 cores, 2.6 GHz frequency each), Intel S2600KP and Intel S2600WT server boards for this processor generation, and the latest Intel SSD DC S3500 solid state drives for enterprise data centers. Resources of this supercomputer will be used not only for relevant scientific research tasks but also for cloud, VDI (Virtual Desktop Infrastructure) and graphical services. The second part of the hybrid HPC complex at SPbPU contains a unique highdense massively parallel RSC PetaStream system with direct liquid cooling and total performance of 258 Teraflops. Polytechnic RSC PetaStream supercomputer has demonstrated LINPACK performance of Teraflops and has 8 th position in the current edition of the local Top50 list. This SPbPU supercomputer system is based on 60-core Intel Xeon Phi 5120D and Intel Xeon E v2 family processors with Intel server boards and Intel SSD DC S3500 solid-state drives for enterprise data centers. Polytechnic RSC Tornado and Polytechnic RSC PetaStream are combined into a single HPC solution at SPbPU supercomputer center with high-speed Infiniband FDR switching network. The new SPbPU supercomputer complex also includes a parallel data storage system with Lustre distributed file system that will support an use up to 1 Petabyte of data and a 0.5 Petabyte block-based storage for cloud environments. Both storages use server technologies based on Intel architecture. New scientific results with RSC PetaStream Various scientific groups actively use RSC PetaStream massively parallel supercomputers with Intel Xeon Phi 5120D and Intel Xeon Phi 7120D processors at St. Petersburg Polytechnic University and Joint Supercomputer Center of the Russian Academy of Sciences (JSCC RAS). This enabled new results in numerous prospective scientific research and achieving priority objectives in fundamental science some of which were presented at ISC 15 conference. Scientists of the Computing Mathematics and Mathematical Geophysics Institute of the Siberian Division of the Russian Academy of Sciences and Novosibirsk State University continue their research in the field of supercomputer modeling of astrophysical processes using RSC PetaStream massively parallel supercomputer and

3 AstroPhi application that they have developed to model astrophysical processes of various scales. Galaxy collision is a regular part of their evolution. On the average any galaxy has up to ten collisions in Hubble time and there is a popular hypothesis stating that collisions of galaxies result in their diversity. Supercomputer modeling is the only way of studying such processes. As the number of supercomputers with hybrid architecture increases, the problem of creating efficient parallel computing methods for such platforms becomes the most important. "Innovative technologies developed by RSC Group specialists and our ability to launch the AstroPhi on a powerful RSC PetaStream supercomputing system with nodes based on Intel Xeon Phi enabled us not only to create a galaxy collision model with record resolution using over a billion design cells but also to conduct new important research in the areas of star formation, supernova effects, cooling, heating and chemical evolution of colliding galaxies. With increased number of logical cores, high performance and scalability of RSC PetaStream provide significant acceleration of the modeling process and significant reduction of time to results with sufficient spatial resolution around 100 parsecs," say Igor Chernykh and Igor Kulikov, scientists of the Computing Mathematics and Mathematical Geophysics Institute of the Siberian Division of the Russian Academy of Sciences and Novosibirsk State University. Scientists of Petersburg Nuclear Physics Institute NRC Kurchatov Institute (PNPI NRC KI) in collaboration with Research Institute of Influenza and St. Petersburg Polytechnic University are researching special influenza virus A modification applicable for a new live vaccine creation. The live vaccine is more effective than inactivated, because immune system fights against real virus. The studied virus is reproducible at Initial structure of NP nonamer NP structure after 200ns low temperatures only (about 26 C) and inactive at human body temperature (37 С). Currently vaccine particular feature is supposed to be connected with amino acid substitution in influenza virus nucleoprotein (NP). Several potential states of NP were simulated with GROMACS MD code on RSC PetaStream massively-parallel supercomputer system. Trajectory analysis is allowed to speak an assumption of reason of virus cold-adaptivity mechanism disorder. For

4 assumption confirmation the consideration of full NP filament structure is needed. NP filament structure "High level of problem scalability was achieved using 64x Intel Xeon Phi processors at RSC PetaStream system down to 50 atoms per thread. With such high scalability level full NP filament simulation becomes available. It s planned to perform on 256x Intel Xeon Phi processors of Polytechnic RSC PetaStream system installed at SPbPU supercomputer center," explain Evgeniy Petukhov, chief manager of SPbPU system software department and Alexey Shvetzov, junior scientist of molecular and radiation biophysics division at St. Petersburg Nuclear Physics Institute. Intel Parallel Compute Center (IPCC) created at the Chemistry Department of Moscow State University with technical support of RSC specialists has received high score at GAMESS(US) benchmarks running on RSC PetaStream supercomputing platform. Their study is devoted to the optimization of GAMESS(US) code for native execution on massively parallel architectures like Intel Xeon Phi. GAMESS(US) is popular open-source quantum chemistry software that is developed and currently maintained by Prof. Mark Gordon group in Iowa State University. This software has officially no threading support which significantly limits its usage on novel parallel architectures. "We studied parallelization of basic quantum chemistry methods like Hartree- Fock and DFT. Calculation of the Fock matrix is the main bottleneck of the Hartree-Fock and to some extent Kohn-Sham DFT methods. We were able to achieve a good scaling of the Fock matrix two-electron contribution code on hybrid MPI/OpenMP regime using up to 1920 threads. This result is very promising and it illustrates that Xeon Phi is well suited for quantum chemistry. The work of this IPCC was among several attempts to run traditional quantum chemistry codes on Intel Xeon Phi. It is remarkable, that the benchmark was done using native regime. Therefore we expect a good scaling also on next generations of Intel Xeon Phi platform," says Vladimir Mironov, senior scientist of the Chemistry Department of Moscow State University. Scientists of the Space Research Institute of the Russian Academy of Sciences and Earth Surveillance System of U.S. National Oceanic and Atmospheric Administration have developed a high performance algorithm for analyzing multispectral images of remote Earth probing (REP) in visible and infrared spectrum to research temperature fields and detect combustion sources on Earth surface. This analysis is very important to fight forest fires, reduce ecological damage from gas flaring at oil fields and rational usage of fishery resources. "In the original version analysis of a single image took over 4000 seconds, but due to code adaptation ad optimization for RSC PetaStream massively parallel system at the Joint Supercomputer Center of the Russian Academy of Sciences, frame processing time was reduced to 12 seconds on 1 st node (based on Intel Xeon Phi 7120D) and to less than 2 seconds on sixteen RSC PetaStream nodes. Therefore, calculation time was reduced by over 2000 times. This provides broad prospects of using the developed data analysis methods for data analysis with latest Suomi NPP, Landsat 8 and GOES-R meteorological satellites," said Mikhail Zhizhin, chief scientist of the Space Research Institutes of the Russian Academy of Sciences. Joint Supercomputer Center of the Russian Academy of Sciences used RSC PetaStream massively parallel supercomputer system to test several applications related to weather forecast. Weather Research and Forecasting (WRF) model has been tested in Conus 2.5 km version. WRF code is developed by a community of scientists including groups from the USA and Great Britain and is broadly used in various weather forecast researches including Russia. Performance measurement at 32 nodes of RSC PetaStream has demonstrated 60% acceleration of theoretically possible value. RSC specialists have migrated SL-AV model developed in Marchuk's Computing

5 Mathematics Institute and Main Computing Center of Roshydromet (Russian Weather Forecast Agency) to RSC PetaStream platform. First performance measurements have shown good parallelism level of the software code performance on 16 nodes of RSC PetaStream has increased by more than three times while the number of threads has increased by 4 times. Specialists of Marchuk's Computing Mathematics Institute have researched performance of new dynamic ocean model with parallelism support based on 3- dimensional decomposition of subject area. First measurements have shown more than 30x acceleration at RSC PetaStream system deployed at JSCC RAS. These results and the above results demonstrate high potential of RSC PetaStream for calculations in the fields of climate science and meteorology.
