ABSTRACT
Fluid mechanical simulation is a typical high-performance computing problem. Due to the development of high-precision parallel algorithms, traditional platforms are unable satisfy requirements large-scale algorithms. The Sunway TaihuLight supercomputer, which uses SW26010 processor as its node, provides powerful performance for this purpose. In paper, hierarchical fluid machinery (swHPFM) framework and algorithm proposed. Using proposed algorithm, engineers can exploit parallelism existing achieve satisfactory on TaihuLight. framework, suitable mapping model system architecture developed, power fully utilized via scratch pad memory (SPM) access strategy serpentine register communication. addition, implemented tested by axial compressor rotor real-world dataset with many-core processors. results demonstrate that we speedup up 8.2×, compared original ported version, only management processing elements (MPEs), well 1.3× an Intel Xeon E5 processor. useful optimization programs heterogeneous architecture.
