13:55 Phys.org Supercomputer Astronomy: The Next Generation

The supercomputer Cray XC50, nicknamed NS-05 "ATERUI II" started operation on June 1, 2018. With a theoretical peak performance of 3.087 petaflops, ATERUI II is the world's fastest supercomputer for astrophysical simulations. ATERUI Ⅱsimulates a wide range of astronomical phenomena inaccessible to observational astronomy, allowing us to boldly go where no one has gone before, from the birth of the universe itself to the interior of a dying star.

07:48 Arxiv.org CS A faster hafnian formula for complex matrices and its benchmarking on the Titan supercomputer. (arXiv:1805.12498v1 [cs.DS])

We introduce new and simple algorithms for the calculation of the number of perfect matchings of complex weighted, undirected graphs with and without loops. Our compact formulas for the hafnian and loop hafnian of $n \times n $ complex matrices run in $O(n^3 2^{n/2})$ time, are embarrassingly parallelizable and, to the best of our knowledge, are the fastest exact algorithms to compute these quantities. Despite our highly optimized algorithm, numerical benchmarks on the Titan supercomputer with matrices up to size $56 \times 56$ indicate that one would require the 288,000 CPUs of this machine for about a month and a half to compute the hafnian of a $100 \times 100$ matrix.

We aim to implement a Big Data/Extreme Computing (BDEC) capable system infrastructure as we head towards the era of Exascale computing - termed SAGE (Percipient StorAGe for Exascale Data Centric Computing). The SAGE system will be capable of storing and processing immense volumes of data at the Exascale regime, and provide the capability for Exascale class applications to use such a storage infrastructure. SAGE addresses the increasing overlaps between Big Data Analysis and HPC in an era of next-generation data centric computing that has developed due to the proliferation of massive data sources, such as large, dispersed scientific instruments and sensors, whose data needs to be processed, analyzed and integrated into simulations to derive scientific and innovative insights. Indeed, Exascale I/O, as a problem that has not been sufficiently dealt with for simulation codes, is appropriately addressed by the SAGE platform.

Shrinking transistors, which powered the advancement of computing in the past half century, has stalled due to power wall; now extreme heterogeneity is promised to be the next driving force to feed the needs of ever-increasingly diverse scientific domains. To unlock the potentials of such supercomputers, we identify eight potential challenges in three categories: First, one needs fast data movement since extreme heterogeneity will inevitably complicate the communication circuits -- thus hampering the data movement. Second, we need to intelligently schedule suitable hardware for corresponding applications/stages. Third, we have to lower the programming complexity in order to encourage the adoption of heterogeneous computing.

Its main operational purpose is Lattice QCD (LQCD) calculations for physics simulations. Quantum Chromo Dynamics (QCD) is the physical theory describing the strong force, one of the four known fundamental interactions in the universe. L-CSC leverages a multi-GPU design accommodating the huge demand of LQCD for memory bandwidth. In recent years, heterogeneous clusters with accelerators such as GPUs have become more and more powerful while supercomputers in general have shown enormous increases in power consumption making electricity costs and cooling a significant factor in the total cost of ownership.

To our knowledge, this is the first exploration of distributed GRPC Tensorflow scalability on a HPC supercomputer at such large scale with synchronous SGD.

For ResNet-50, we achieve >80% scaling efficiency on up to 128 workers, using 32 parameter servers (PS tasks) with a steep decline down to 23% for 512 workers using 64 PS tasks.

11:29 Ixbt.com Intel отказывается от планов по выпуску нового поколения ускорителей Xeon Phi в пользу совершенно новой платформы для Exascale computing

Компания Intel опубликовала пресс-релиз, посвящённый её планам касательно сегмента Exascale computing. Этим термином обозначаются суперкомпьютеры с производительностью свыше 1 exaFLOPS. Если верить документу, первая такая система должна появиться в Китае ещё к 2020 году. Затем подобные суперкомпьютеры появится в США и Европе. Для сравнения, на данный момент самым производительным суперкомпьютером является Sunway TaihuLight с показателем «всего» 93 PFLOPS или 0,093 exaFLOPS. Причём он почти втрое опережает своего ближайшего конкурента. Также Intel упомянула, что в рамках инициативы по развитию данного направления компания отказывается от выпуска в будущем ускорителей Xeon Phi поколения Knights Hill. Формально они были представлены ещё в 2014 году, но появиться должны были бы в 2018 или 2019. Это 10-нанометровые решения, которые планировались, как смена

Supercomputer building is a many sceene, many authors game, comprising a lot of different technologies, manufacturers and ideas. Checking data available in the public database in a systematic way, some general tendencies and limitations can be concluded, both for the past and the future. The feasibility of building exa-scale computers as well as their limitations and utilization are also discussed. The statistical considerations provide a strong support for the conclusions.

Researchers have used the Stampede1 and 2 supercomputers to complete one of the world's largest earthquake simulation models: The Uniform California Earthquake Rupture Forecast (UCERF3). The simulations showed that in the week following a magnitude 7.0 earthquake, the likelihood of another magnitude 7.0 quake in California would be up to 300 times greater than the week before.

16:13 Phys.org Using supercomputers to delve into the building blocks of matter

Nuclear physicists are known for their atom-smashing explorations of the building blocks of visible matter. At the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, and the Large Hadron Collider (LHC) at Europe's CERN laboratory, they steer atomic nuclei into head-on collisions to learn about the subtle interactions of the quarks and gluons within.

13:10 Phys.org Supercomputer simulation of chaotic circuits

It's really surprising that many simple electronic circuits built of just a few components behave chaotically, in an extremely complicated, practically unpredictable manner. Physicists from the Institute of Nuclear Physics Polish Academy of Sciences in Cracow have discovered, examined and described dozens of new, unusual circuits of this type. What is especially interesting is that one of the circuits generates voltage pulses very similar to those produced by neurons, only it does so a thousand times faster.

Astrophysicist Chris Fryer was enjoying an evening with friends on August 25, 2017, when he got the news of a gravitational-wave detection by LIGO, the Laser Interferometer Gravitational-wave Observatory. The event appeared to be a merger of two neutron stars—a specialty for the Los Alamos National Laboratory team of astrophysicists that Fryer leads. As the distant cosmic cataclysm unfolded, fresh observational data was pouring in from the observation—only the fifth published since the observatory began operating almost two years ago.
