英文摘要: Large-scale simulation of the thermal convection in the Earths outer core is studied. Starting from a legacy parallel code using Aztec and MPI, two optimized codes have been developed based on the PETSc software package. The first version gains several times acceleration with the help of the block-Jacobi preconditioners and the well-optimized libraries provided in PETSc. The second version, aiming at better parallel scalability, is developed based on the ideas of domain decomposition method for multi-physical problems. Test results employing thousands of processor cores on three supercomputers, i.e., an IBM BlueGene/L, a Dawning 5000A and a Lenovo DeepComp 7000, are provided. © 2010 IEEE.
