CFD users of supercomputers usually resort to rule-of-thumb methods to select the number
of subdomains (partitions) when relying on MPI-based parallelization. One common …

This work presents a comprehensive performance analysis and optimization of a multiscale
agent-based cellular simulation. The optimizations applied are guided by detailed …

Permafrost, ie, soil that is year-round frozen in depth, is covering a quarter of the continents
of the northern hemisphere. It currently experiences fast changes due to climate change at …

This paper presents an optimized framework for simulating aeroacoustic flow on
unstructured meshes. The libFastMesh (LFM) framework is based on a low-dissipation finite …

Urban air quality issues are closely related to human health and economic development. In
order to investigate street-scale flow and air quality, this study developed the atmospheric …

Fast and accurate evaluation of aerodynamic characteristics is essential for aerodynamic
design optimization because aircraft programs require many years of design and …

This paper presents a novel methodology to optimize high-performance computing
hardware selection and allocation for Computational Fluid Dynamics (CFD) simulations …

Driven by the emergence of Graphics Processing Units (GPUs), the solution of increasingly
large and intricate numerical problems has become feasible. Yet, the integration of GPUs …

Automated code instrumentation, ie the insertion of measurement hooks into a target
application by the compiler, is an established technique for collecting reliable, fine-grained …

In this paper, we present a thorough performance analysis of a highly parallel Monte Carlo
code for modeling global erosion and redeposition in fusion devices, ERO2. 0. The study …
