Title:

Applications and Challenges of High-Performance Computing Accelerated by GPU Clusters in Engineering Simulation

Abstract:

As the demand for computational resources in engineering simulation continues to grow, high-performance computing (HPC) accelerated by GPU clusters has emerged as a pivotal force at the forefront of technology. This report provides an in-depth analysis of the widespread applications, significant advantages, main challenges, and future trends of GPU cluster-accelerated HPC in engineering simulation. By parallel processing vast amounts of simulation data, GPU clusters can significantly enhance the speed and efficiency of engineering simulation tasks, thereby accelerating product design cycles and boosting innovation efficiency. The report begins by introducing the basic architecture of GPU cluster acceleration technology and its support mechanisms for parallel computing. It then discusses how this technology plays a crucial role in fields such as fluid dynamics simulation, structural strength analysis, composite material behavior prediction, and the development of new energy systems. These application cases highlight the unique advantages of GPU clusters in handling complex, large-scale computational tasks. Furthermore, this report explores the challenges faced in implementing GPU cluster-accelerated HPC, including the requirements for advanced programming skills, algorithm optimization, resource management, and scheduling. An assessment of existing solution strategies suggests the use of advanced programming frameworks and the adoption of machine learning technologies to automate and optimize the process. Finally, the report looks forward to the application prospects of GPU cluster-accelerated HPC in future engineering simulations, emphasizing its potential in enhancing computational efficiency, fostering interdisciplinary research, and developing more complex simulation models. With technological advancements and continuous optimization of algorithms, GPU cluster-accelerated high-performance computing is expected to play an increasingly central role in the field of engineering simulation, driving scientific research and technological innovation to new heights.

Title:

A Learnable Behavioural Model for Crisis Management Simulation

Abstract:

Simulation of evacuations in emergencies is crucial in preparing authorities to mitigate disastrous outcomes from unforeseen crises. In an effort to increase the effectiveness of such critical systems, several works have attempted to introduce intelligence in Multi-Agent Systems (MAS) for crisis simulation by incorporating psychological behaviours learned from the social sciences or by using data-driven machine learning models with predictive capabilities. We borrow from Social Sciences behind human characteristics to design a Conscious Movement Model (CMM) to dynamically reflect human behaviour in crisis situations. We then introduce a novel methodology to train this CMM model through pedestrian tracking from video footage using a CMMA (Conscious Movement Memory Attention) model. The trained behaviour model can then be used to inject realism in the crisis simulation. Experimental results on real-life case studies of emergency evacuations show that we can produce realistic simulations similar to actual results, performing better than state of the art methods.

Title:

Molecular Dynamics Study on Structure Formation in Soft Matter and Biomolecules

Abstract:

The structure formation in soft matter, such as polymer crystallization and self-assembly of amphiphilic molecules, and  biomolecules, such as structural change at radiation-induced clustered DNA damage, has been extensively studied. Polymeric materials have various mechanical and thermodynamical properties since polymer chains show diverse static and dynamical structures. The self-assembly phenomena of amphiphilic molecules, such as lipids and surfactants, in a solution are of great significance in many biological and industrial processes. In addition, radiation-induced clustered DNA damage can have significant biological consequences, but the underlying molecular mechanisms remain unknown. With a view to investigating the structure formation in soft matter and biomolecules at the molecular level, we have performed the molecular dynamics simulations of several cases: (i) an isolated single polymer chain, (ii) isolated short chain molecules, (iii) a single polymer chain in a solution, (iv) amphiphilic molecules in a solution at various concentrations, and (v) clustered damaged DNA. Detailed analysis of the structure formation processes in (i)-(iv) reveals two common features of the nonequilibrium dynamics in chain molecules and amphiphiles: stepwise energy relaxation and dynamic coexistence. Moreover, in (v), the effects of clustered DNA damage on DNA structure and dynamics were examined for damaged DNA with two apurinic/apyrimidinic (AP) sites. The results show that the cluster insertion of the two AP sites has a significant impact on the local and global structure of DNA. This suggests that the present case with clustered AP sites may have a non-negligible impact on the biological function of damage repair.
