NASA Earth Exchange (NEX) Earth Science Division/NASA Advanced Supercomputing (NAS) Ames Research Center

NASA Earth Exchange (NEX) Project Goal To improve availability of Earth Science data, models, analysis tools and scientific results through a platform that fosters knowledge sharing, collaboration, innovation and direct access to compute resources.

NASA Earth Exchange components

NEX Resources § Computing § Supercomputing and storage through NASA Advanced Supercomputing Division (NAS) § Almost 3 PB storage, 512 - 8, 000 CPU cores § Possible to extend far beyond 8, 000 cores if needed § Data § Global MODIS, AVHRR, Landsat, GCM Scenarios, weather data, etc. § Models § Publicly available models § Software Utilities § Open source and commercial (pending licensing) § Collaboration Facilitation/Knowledge Network § Based on DASHlink social network site § Audio/Visual Real-time Collaboration (Adobe Connect) § Large-scale Data visualization at NAS on hyperwall-2 + building custom visualization facility

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

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
