empirically fitted energy functions. The 8 full papers presented in this book were carefully reviewed and selected from 22 submissions. So for many “real” applications the performance on the TaihuLight will be no where near the peak performance rate. The TianHe-1A supercomputer: its hardware and software.
Significantly, the computer only uses Chinese-designed chips, reducing the country’s reliance on US technology and marking a significant achievement for the country. Redmond: Microsoft Research, 2009Shingu S, Takahara H, Fuchigami H, et al. Sunway TaihuLight: The system and applications Zhao Liu Director of Application Support Department National Supercomputing Center in Wuxi. Sunway TaihuLight [3], a supercomputer that ranks first in the world currently, is powered by the SW26010 many-core processors with a total computing capacity of over 100 PFlops. Our experimental results show that the effect of the cooperative computing techniques of CPEs is significant, with DGEMM (double-precision matrix multiplication) achieving an efficiency of 94%, FFT (fast Fourier transform) obtaining a performance of 207 GFLOPS and FDTD (finite-difference time-domain) obtaining a performance of 27 GFLOPS.On June 17, 2013, MilkyWay-2 (Tianhe-2) supercomputer was crowned as the fastest supercomputer in the world on the 41th TOP500 list.
The ANN is trained on a large set of atomic structures After its initial development, Aladyn was evaluated the atomic interactions in materials with the accuracy of the more expensive quantum This paper provides an overview of the MilkyWay-2 project and describes the design of hardware and software systems.

Porting large codes to An extreme-scale implicit solver for complex PDEs: highly heterogeneous flow in earth’s mantle. Applications that have already been used on the system include “a fully-implicit nonhydrostatic dynamic solver for cloud-resolving atmospheric simulation,” “a highly effective global surface wave numerical simulation with ultra-high resolution,” and a “large scale phase-field simulation for coarsening dynamics based on Cahn-Hilliard equation with degenerated mobility.”
The name is translated as divine power, the light of Taihu Lake.
In contrast with other existing heterogeneous supercomputers, which include both CPU processors and PCIe-connected many-core accelerators (NVIDIA GPU or Intel Xeon Phi), the computing power of TaihuLight is provided by a homegrown many-core SW26010 CPU that includes both the management processing elements (MPEs) and computing processing elements (CPEs) in one chip. Some aspects of atmospheric dynamical cores atomistic simulations. In: Proceedings of the International Conference on High Performance Computing, Networking, Storage and Analysis.
Prominent improvements include alleviated double Intertropical Convergence Zone problem, increased marine boundary layer clouds, and better El Niño Southern Oscillation amplitude and periods. Thank you! You can also search for this author in
And it is the main building-block of the current world's third fastest supercomputer: Sunway Taihu Light Join ResearchGate to find the people and research you need to help your work.This report provides a description and performance evaluation of the optimization
MilkyWay-2 supercomputer: system and application. The numerical algorithm is the parallel Barnes-Hut tree algorithm, which has been used in many large-scale astrophysical particle-based simulations. SZ and ZFP are two leading BSD licensed open source C/C++ libraries for compressed floating-point arrays that support high throughput read and write random access. You can also search for this author in To maximize accuracy and minimize runtime, the solver incorporates a number of advances, including aggressive multi-octree adaptivity, mixed continuous-discontinuous discretization, arbitrarily-high-order accuracy, hybrid spectral/geometric/algebraic multigrid, and novel Schur-complement preconditioning.
Int J High Perform Comput Appl, 2012, 26: 74–89Lauritzen P H, Jablonowski C, Taylor M A. We propose a generalized partition scheme of the problem domain, so as to keep a balanced utilization of both CPU resources and accelerator resources.
Now the country has 167 systems, beating the US’ 165 systems - the first time any nation has bested America on the list.According to China’s official national plan, the country aims to develop an exascale computer (Tianhe-3) during the 13th Five-Year-Plan period (2016-2020). In (b), the initial computation of Part-A and the final computation of Part-C at the last time have been moved outside. DFMC integrates management processing elements (MPEs) and computing processing elements (CPEs), which are heterogeneous processor cores for different application features with a unified ISA (instruction set architecture), a unified execution model, and share-memory that supports cache coherence. As a result, there is no computation dependence among these three parts within one loop.The global (a) and regional (b) distributions of the simulated significant wave height on January 5, 2011.
