  1. GeoFramework: Example of using frameworks in geophysics Tectonic Modeling Workshop June, 2005 Mike Gurnis Caltech

  2. A hierarchy of software components ? Superstructure ? Geodynamic Specific ? Infrastructure ? Library

  3. Superstructure and Geodynamic Specific Layers • Simulation controller • Monitor Simulation • Couple Fluid to Solid Superstructure • Component A • Component B • …. Geodynamic Specific

  4. framework service service service service solver solver infrastructure component component component bindings bindings bindings engine engine library Pyre Framework (Science Neutral) The integration framework is a set of co-operating abstract services python package abstract class specialization FORTRAN/C/C++ Developed by Michael Aivazis

  5. GeoFramework TECTON Solver

  6. Virtual Test Facility (VTF): Example From Pyre

  7. CitcomS main Parser Mesher Stokes solver T solver Output

  8. Ouput.py Mesher.py Vsolver.py TSolver.py Pyre version of CitcomS regionalcitcoms.py Components (Python) Python bindings Mesher Stokes solver T solver Output RegionalModule.so (a shared object)

  9. CitcomS.py as a single component

  10. Coupling With Pyre

  11. Regional and Global Mantle Flow Coupled with Pyre CitcomS.py, Eh Tan

  12. Regional CitcomS coupled to full CitcomS CitcomS.py, Eh Tan

  13. Predictions: Hot-spot track & synthetic tomography

  14. Example: Mantle convection coupled to lithosphere • Monitor Simulation • Couple Fluid to Solid • Visualization Superstructure • Self-contained geophysics (single phyiscs) • Rheology modules Geodynamic Specific • Mesher: Solid & Fluid • Solver: Solid & Fluid Infrastructure Library: PETSc, BLAS, MPI

  15. Example of Geodynamic Specific & Infrastructure Layers • SNARK -- particle based FEM with implicit solver • SNAC -- Lagragian explicit FEM Geodynamic Specific • StGermain: A framework with entry points & plugins for: building meshes, advecting particles, calling solvers, I/O….. Infrastructure Library: PETSc, MPI

  16. Example of Geodynamic Specific & Infrastructure Layers Geodynamic Specific SNARK: Monash group (Moresi) SNAC: Caltech/Texas groups (Gurnis, Lavier) • SNARK -- particle based FEM with implicit solver • SNAC -- Lagragian explicit FEM Infrastructure: Software Engineers at the Victorian Partnership for Advanced Computing (Steve Quenette Team Leader) • StGermain: A framework with entry points & plugins for: building meshes, advecting particles, calling solvers, I/O…..
