  7. The Power of GEON Cluster Nodes Current model (2-nodes, 4CPUs) Original model (single CPU) (x 40 vertical topographic exaggeration) • More than 800,000 unstructured elements • Major Faults and more deformation zones • Subduction zone • 21 layers in R-direction • 15 min per time step • Less than 3000 elements • Three layers in R-direction • 2 min for per time step www.geongrid.org

  8. The fine mesh allows important details to be included in the model www.geongrid.org

  9. Automatic domain decomposition for parallel computing www.geongrid.org

  10. Automatic data partitioning and communication among sub-domains Domain partitioning with minimized inter-boundaries (blue area) for parallel communication www.geongrid.org
