GeoFramework: Example of using frameworks in geophysics

Explore the GeoFramework example of using frameworks in geophysics, specifically in tectonic modeling workshop of June 2005 led by Mike Gurnis at Caltech. The workshop delves into a hierarchy of software components, Superstructure, Geodynamic Specific layers, and infrastructure library. Discover the Pyre framework, GeoFramework TECTON Solver, and CitcomS integration among other geophysical tools and services.

  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…..
