5. Knowledge Network  Users can search for related activities  Who is doing what where?  Map interface  Categorized by discipline  Categorized by geographic region  Users can create projects and link to other projects  Users can control the visibility of their project  Users can control access to the project and the level of sharing  Users can share algorithms, data, knowledge  Users can search for related activities  Who is doing what where?  Map interface  Categorized by discipline  Categorized by geographic region  Users can create projects and link to other projects  Users can control the visibility of their project  Users can control access to the project and the level of sharing  Users can share algorithms, data, knowledge

6. Example End-to-End Usage  User registers and specifies resource requirements:  Data, tools, models and computing resources  A custom environment is created containing the requested resources  Within this environment user can:  Run existing models  Bring in new data, models, and algorithms  Extend existing models  Share models and data with community  Provide access to the results and the environment  When work is completed resources are recycled  The specific environment (including models, data, etc.) can be completely saved and reloaded and re-run in the future reproducing the results  User registers and specifies resource requirements:  Data, tools, models and computing resources  A custom environment is created containing the requested resources  Within this environment user can:  Run existing models  Bring in new data, models, and algorithms  Extend existing models  Share models and data with community  Provide access to the results and the environment  When work is completed resources are recycled  The specific environment (including models, data, etc.) can be completely saved and reloaded and re-run in the future reproducing the results
