Resumo
Multi-physics simulations are essential for the academy and industry, helping understand how multiple physical phenomena behave in a given context. With the growth of the HPC market and the consequent greater accessibility to more advanced and powerful hardware, extensive use of parallelization became a widespread scenario in multi-physics simulations. This situation creates a problem of proper load distribution, which, in this case, is complicated by the already complex nature of multi-physics simulations. In this work, we propose multiple approaches to the load-balancing problem in contrast to the more traditional single-approached solutions. This proposition was implemented for the computational fluid dynamics (CFD) code MFSim, which uses block-structured adaptive mesh and validated using three industrial-scale cases and one academic.
Abstract
Multi-physics simulations are essential for the academy and industry, helping understand how multiple physical phenomena behave in a given context. With the growth of the HPC market and the consequent greater accessibility to more advanced and powerful hardware, extensive use of parallelization became a widespread scenario in multi-physics simulations. This situation creates a problem of proper load distribution, which, in this case, is complicated by the already complex nature of multi-physics simulations. In this work, we propose multiple approaches to the load-balancing problem in contrast to the more traditional single-approached solutions. This proposition was implemented for the computational fluid dynamics (CFD) code MFSim, which uses block-structured adaptive mesh and validated using three industrial-scale cases and one academic.
