  1. CIG - Serving the Community Bill Appelbe, Chief Scientist VPAC

  2. Outline • Software Conclusions and Workshop Observations • What will CIG NOT do! • What can CIG do for you?

  3. Software Conclusions& Workshop Observations • The number of computational codes in wide use across this community is not great • Tecton (Lithomop/Pylith) and FLAC • CIG is already working on putting these into the CIG framework! • With mechanisms to allow you to customize/extend these • Dalhousie’s ALE code • Lot’s of options on how it might be contributed/engaged • The community seems to be okay/ripe for consolidation of community computational codes

  4. Software Conclusions& Workshop Observations (cont.) • A better geophysical characterization of what codes are good for what would be very useful • And what extensions have been made to codes, what works and what does not • Once CIG software repository gets operational, a process for the community to contribute is needed • Improvements/fixes for CIG software • New codes for the CIG repository • Reviews by users and benchmarks

  5. Software Conclusions& Workshop Observations (cont.) • There is widespread interest in benchmarking • Suzanne’s presentation • Benchmarking is widely used in other communities • SPEC, TPA • Benchmarking really helps us (developers) • Especially if the user community and developers collaborate on these • They give us “targets” and “tests” for code development • Benchmarking really helps users • Selecting the right code for new problems • Correlation with observations (physical models) • Strengths and weaknesses of codes

  6. Software Conclusions& Workshop Observations (cont.) • Trends in scientific issues and their relations to models • Model coupling (muliphysics) for • Surface and lithospheric processes • Magmatic and lithospheric processes • Embedding models with different resolutions • More complex models: thermal, viscous, plastic, elastic combined • 3D (and models with higher resolution) • Inversion??

  7. What will CIG NOT do! • Your research • We build infrastructure to support research • Write new solvers • Discourage development of new solvers • Such as GObjects • Determine community science priorities • The user community, resources, and development costs should determine what goes into the framework

  8. What CIG Can do • Put established codes into the framework • Level of support may vary (Gold, Silver, Bronze) • Based on maturity/stability/usage of codes • Provide training and documentation • Support developer contributions of new code and user models and reviews • Foster and support community collaboration • Benchmarking • Web communities (wiki’s, plumes) • Repositories of models (code, input, output, papers) • Provide funding leverage • CIG’s resources are very limited, so we need to leverage all we can
