Supercomputing technology has been evolving rapidly in an accelerated way. It has made a significant impact on scientific research, technology innovation, economic and social development, and the life of ordinary people. Over the past three decades, China has devoted considerable efforts on the development of supercomputing technologies, and made tremendous and remarkable achievements in this field. China's supercomputing systems now rank among the world's most powerful supercomputers. As Moore's Law approaches its limit, the development of exascale supercomputing systems is facing a series of grand challenges in both technologies and applications. Based on the experiences of China's supercomputing development over the past years, this paper analyzes the major technical challenges on the path towards exascale computing. Additionally, ongoing major R&D activities on next-generation supercomputing in China are introduced, and the possible solutions to achieve exascale computing, including co-design and convergence computing, are discussed.

“…The thought has a curious coincidence with computational thinking, but it is more specific, vivid, maneuverable and executable compared to the latter. Xu et al presented that the computational lens and computational thinking lead to the emergence of a new computer science that is more universal and fundamental than the previous one in 2011, and the computer science is experiencing fundamental transformations, from its scope, objects of study, basic metrics, main abstractions, fundamental principles, to its relationship to other sciences and to the human society [19,20,21]. It happens that there is a similar case.…”

The volatile global shipping market puts forward the higher requirements to the container terminal logistics systems (CTLS) than ever, especially in terms of programming, planning, scheduling and decision. The computational logistics provide a systematic methodology to overcome the issues that differs from traditional approaches distinctly. This paper discusses the theoretical framework, important components and core concept of computational logistics, and then presents the container terminal logistics generalized computation design, implement, execution, analysis and evaluation hierarchy (LGC-DIE-AEH) by the integration of the computational lens and computing principles to explore the computational logistics in the field of CTLS. Subsequently, the execution performance of a quay crane farm at a regional container hub terminal in China is analyzed and evaluated by LGC-DIE-AEH. The crane performance evaluation core indicator framework (CPE-CIF) is proposed by the fusion of the design philosophy and underlying principles of computing architecture, operating system, and virtual machine by computational lens. The CPE-CIF help us to find out the advantages, disadvantages and improvement directions of quay crane farm operation. That illustrates and verifies the feasibility and credibility of LGC-DIE-AEH from the perspective of the practice of container terminal decision-making support at the tactical level.

“…simulations which involve either very computationally-intensive algorithms and/or very large datasets ('big data') were once restricted to being carried out on large, expensive supercomputers. The past twenty years has seen a dramatic rise in the use of distributed computing, fast desktop PCs, and GPU cluster supercomputers, together with a sharp drop in the overall implementation and running costs for 'big physics'-capable computation; see for example Fernández, Fernández, Miguel-Dávila, Conde, and Matellán (2019) and Xu, Chi, and Xiao (2016).…”

Traditional practical work for higher education in STEM subjects is under pressure from rising student numbers and adesired increase in active learning. Investing in more buildings and staff is financially challenging, while stretching existing resources affects outcomes, health, and participation. A more pragmatic approach is to embrace a less instrumentalist view of practical work in physical spaces and instead adopt a critical post-humanist approach which mixes both humanity and technology to achieve a sum greater than the parts, not bound by the limits of either. We share the experiences of leading UK exponents of non-traditional laboratories in the four main categories of simulation, virtual laboratories, real-asynchronous, and realsynchronous activities, as well as experts in scaling digital education initiatives for university-wide adoption. We foreshadow opportunities, challenges and potential solutions to increasing the opportunity for active learning by students studying at traditional campuses, via the complementary addition of non-traditional practical work.
