Extreme-scale numerical simulations seriously demand extreme parallel computing capabilities. To address the challenges of these capabilities toward exascale, we systematically analyze the major bottlenecks of parallel computing research from three perspectives: computational scale, computing efficiency, and programming productivity. For these bottlenecks, we propose a series of urgent key issues and coping strategies. This study will be useful in synchronizing development between the numerical computing capability and supercomputer peak performance.

Strategic Study of CAE 2000, Volume 2, Issue 1, Pages 68-72
In this paper, the relationship between the ultra large scale integrated circuits (ULSI) and high purity water and the demands for water quality are described.Several key new techniques of high purity water fabrication are studied. A method for improving the quality of high purity water is proposed, which can effectively decrease the concentrations of total organic carbon (TOC), bacteria and bacterial endotoxins and dissolved oxygen.The contamination of high purity water caused by various pipe materials is described.Some data and examples of author´s experiments are also included.

Strategic Study of CAE 2013, Volume 15, Issue 8, Pages 4-11
The Fourth Nanjing Yangtze River Bridge is the first suspension bridge of three-span steel box girder using continuity and flexible bearing system with a main span of 1418 m, and makes use of the flexible bearing system and distributional force transmission system with main rope for the first time. It overcomes the deep foundation design and construction technical problems of oversized "∞" shape diaphragm wall and ultra-large well-sinking under complicated geological conditions, proposes the technologies of main rope mixed-knit and argon-rich gas shielded arc welding, and uses the pavement technique of compound gussasphalt at steel bridge deck. Additionally, it utilizes synthetical technique to control construction quality of bulk mass concrete. This text summarizes the construction management and key technical innovation.

Inspired by the design philosophy of information metasurfaces based on the digital coding concept, a planar 4-bit reconfigurable antenna array with low profile of 0.15 λ0 (where λ0 is the wavelength) is presented. The array is based on a digital coding radiation element consisting of a 1-bit magnetoelectric (ME) dipole and a miniaturized reflection-type phase shifter (RTPS). The proposed 1-bit ME dipole can provide two digital states of “0” and “1” (with 0° and 180° phase responses) over a wide frequency band by individually exciting its two symmetrical feeding ports. The designed RTPS is able to realize a relative phase shift of 173°. By digitally quantizing its phase in the range of 157.5°, additional eight digital states at intervals of 22.5° are obtained. To achieve low sidelobe levels, a 1:16 power divider based on the Taylor line source method is employed to feed the array. A prototype of the proposed 4-bit antenna array has been fabricated and tested, and the experimental results are in good agreement with the simulations. Scanning beams within a ±45° range were measured with a maximum realized gain of 13.4 dBi at 12 GHz. The sidelobe and cross-polarization levels are below –14.3 and –23 dB, respectively. Furthermore, the beam pointing error is within 0.8°, and the 3-dB gain bandwidth of the broadside beam is 25%. Due to its outstanding performance, the array holds potential for significant applications in radar and wireless communication systems.
