Algebraic multi-grid (AMG) is increasingly used for large practical problems, its parallelization is highly demanded. A parallel algorithm to enhance the robustness and performance for AMG was proposed with regard to unique characteristics of partial differential equations governing fluid flows. A building strategy was developed to accomplish grid coarsening and build the hierarchy of multi-level grids. Moreover an agglomeration approach was proposed, which stems from the consideration of both the physical and mathematical properties of flow fields. The parallelized AMG has demonstrated excellent performances and strong enhancement on many cases.
