Workshop “Multi-scale, Multi-physics and Coupled Problems on highly parallel systems (MMCP)” HPC Asia 2023

The workshop will gather researchers (computer scientists, engineers, mathematicians, physicists, chemists, biologists, material sciences etc.) working on different disciplines but all facing challenges in multi-scale and multi-physics as well as coupled simulations on HPC systems.

Applications with different characteristics in parts of the computational domain can lead to unexpected performance issues. The optimum setting for one part might be contradictory to the optimum for another; the overall optimum might be a non-optimal, but still a satisfactory compromise for researchers.

Several approaches have been examined while developing different solutions, depending on the application and hardware combination. On the application side, monolithic or partitioned approaches have been introduced; on the hardware side, homogeneous and heterogeneous cluster settings. All combinations have advantages and disadvantages, all leading to the following question: how to find the optimal configuration and setting of all parameters, with respect to quality of solution vs. computational efficiency?

The goal is – of course – the performance and efficiency of each component (region or solver), but the characteristics of other scales, other physical phenomena might change the game. Also, a coupling tool might introduce, e.g., load imbalances or hinder the overlapping of communication and computation.

The focus of the workshop will be on computational issues regarding performance and suitability for high-performance computing. Furthermore, the underlying strategies to enable large simulations will be highlighted.

Keeping these aims in mind, contributions from all aspects of engineering applications will be considered. Topics of applications will include (but are not be limited to):

• Multi-scale problems
• Multi-physics problems
• Molecular Dynamics
• Multi-Domain/Concurrency
• Multi-scale and/or multi-physics modelling for biomedical or biological systems
• Novel approaches to combine different scales and physics models in one problem solution
• Challenging applications in industry and academia, e.g. turbulence and multiphase flows, fluid-structure interactions, chemical engineering, material science, biophysics, automotive industry, …
• Load balancing
• Adaptivity
• Heterogeneous architectures
• New algorithms for parallel-distributed computing, specific to this topic.
