Topology-Aware Communication Optimization

Topology-Aware Communication Optimization for OpenFOAM This repository provides an OpenFOAM-12 utility for topology-aware communication optimization in parallel CFD simulations on NUMA-based HPC systems. The tool improves communication performance by: - Optimizing MPI rank-to-core placement based on the communication graph induced by the mesh decomposition- Introducing a hierarchical global reduction schedule aligned with the hardware topology
