CIG Software VisionCIG Software VisionCIG Software VisionCIG Software Vision

• Open source, well documented & supported, and easily verified

• A framework of common components that allow different physics and methods to be easily coupled

• Enable individual scientists to build and explore new models

• Scalable from Laptops to Supercomputers

Mid-Ocean Ridge Dynamics

Reactive Channel formation

• Multi-physics: adds fluids to a range of solid models (both mantle and lithosphere)– Interoperability with other CIG codes?

• Multi-scale– Magmatic regions embedded in large

scale mantle dynamics– Localization phenomena in magmatic

regions– Grain Scale physics?

• Necessary for integrating models with Observations (particularly geochemistry and plate-boundary dynamics)

• Important for large class of users and developers, particularly MG&G (Ridges/MARGINS etc.)

• Progress, however, requires significant increase in flexibility of software tools.

Overarching Workshop QuestionsOverarching Workshop QuestionsOverarching Workshop QuestionsOverarching Workshop Questions

• What are the important/interesting scientific and computational problems we want to solve?

• What can we do today? (what is the current state of theory and computation in magma dynamics)

• What do we want to do tomorrow?• How do we get there?• How can CIG help?

• An open Discussion Workshop• Goal: answer these questions and deliver

concrete proposals to CIG
