“…It is expected that the first exascale supercomputer will be debuted in around 2021, which will open the exascale era for high performance computing (HPC). However, because of the slowdown of both Moore's law [1] and Dennard Scaling law [2], the improvements of system performance and efficiency are becoming increasingly difficult, bringing unprecedented challenges on architecture design for exascale supercomputer [3][4][5][6][7][8][9][10][11][12]. As one of the leading teams of supercomputer research and development in China, Sunway has solid foundations on both theoretical research and engineering practice on the supercomputer design, which has been proven by the successful implementations of Sunway BlueLight [13,14], Sunway TaihuLight [15][16][17][18][19] and Sunway exascale prototype.…”

In recent years, the improvements of system performance and energy efficiency for supercomputers have faced increasing challenges, which create more intensive demands on the architecture design for realizing exascale computing. This paper first analyzes the main requirements of exascale computing on the aspects of the parallel computing application and supercomputing center operation. Afterwards, a mapping scheme of "demands-challenges-architecture" is proposed. Then, the major challenges of exascale supercomputer, such as scalability, power consumption, data movement, programming and availability, are thoroughly analyzed, and the corresponding appropriate solutions are proposed. Moreover, this paper proposes the Sunway computer architecture towards exascale computing in which the many-core processor, network chipset and software system are all domestically-designed. The technology roadmap of Sunway supercomputer will hold the comprehensive design methods for the architecture, including the processor, interconnect network, assembly structure, power supply, cooling system, system software, parallel algorithm and application support, promising great advances for exascale supercomputing.

“…Scalability, besides high performance and fault tolerance, is an important feature of modern applications (Tanenbaum & van Steen, 2006;Alvin et al, 2010;Lavinia, Dobre, Pop, & Cristea, 2011). Scalable software applications may be distributed over nodes of a multicomputer.…”

Scalability and fault tolerance are important features of modern applications designed for the distributed, loosely-coupled computer systems. In the paper, two-layer scalable structures for storing data in a distributed RAM of a multicomputer (SD2DS) are introduced. A data unit of SD2DS (a component) is split into a header and a body. The header identifies the body and contains its address in a network. The headers are stored in the first layer of SD2DS, called the component file, while the bodies are stored in the second layer, called the component storage. Both layers are managed independently. Details of the management algorithms are given, along with SD2DS variant suitable for storing plain records of data. The SD2DS is compared to similar distributed structures and frameworks. Comparison considerations together with test results are also given. The results proved superiority of SD2DS over similar structures.

“…The race seems to remain competitive. The United States has already laid out a plan to produce a machine capable of performing 10 18 floating point operations per second (or exaFLOPS) by the end of this decade, i.e., machine 1,000 times faster than Roadrunner [1,2]. Japan, China, Russia, and the European Union also plan to produce the exascale machine in the near future.…”

The last decades have witnessed an increasingly indispensible role of high performance computing (HPC) in science, business and financial sectors, as well as military and national security areas. To introduce key aspects of HPC to a broader community, an HPC session was organized for the first time ever for the United States and Korea Conference (UKC) during 2012. This paper summarizes four invited talks that each covers scientific HPC applications, large-scale parallel file systems, administration/maintenance of supercomputers, and green technology towards building power efficient supercomputers of the next generation.
