SC11 Science Gateway Group Overview
- 1. The Indiana University Science Gateway Group: Advancing Web-based scientific research • The IU Science Gateway Group supports gateway development activities at IU and world-wide. • Marlon Pierce: Group Lead • Suresh Marru: Principal Software Architect • Raminder Singh, Chathura Herath, Yu Ma, Lahiru Gunathilake: Senior team members • Six interns and research assistants • More Info & Contact • http://pti.iu.edu/sgg • Marlon Pierce: mpierce@cs.indiana.edu • Suresh Marru: smarru@cs.indiana.edu 1
- 2. Group Activities • Research & development of scientific portal interfaces and frameworks; distributed application and workflows; messaging and gateway development tools & API’s. • Fostering e-Science software sustainability through Apache Software Foundation • Open community, not just open source • Apache Airavata: software for scientific workflows • http://airavata.org • Apache Rave: Web and Social Networking mashup engine • http://incubator.apache.org/rave/ • We work with gateways across the nation • Lead the Open Gateway Computing Environments: NSF funded partnership • Lead the XSEDE Extended Collaborative Support Services’ gateway support activities. 1

- 4. Apache Airavata • Science Gateway software framework to: – compose, manage, execute, and monitor computational workflows – web service abstractions to legacy command line scientific applications – support for computational resources ranging from local resources to computational grids and clouds – modular software framework to use as individual components or as an integrates solution.
- 5. Apache Airavata High Level Overview
- 7. Apache Rave: Open Community Software for Social Networking, Shareable Web Components, and Science Gateways • Rave is an Apache Software Foundation incubator project. • Software for managing OpenSocial Gadgets and W3C Widgets • Founding members: • Mitre Software • SURFnet • Hippo Software • Indiana University • More information • Project Website: http://incubator.apache.org/rave/ • Mailing List: rave-dev@incubator.apache.org 1
- 8. What is Rave? • Rave is a downloadable Web portal • Written in Java, JavaScript • Based on Spring MVC framework • Builds on Apache OpenSocial spec for social networking Web gadgets, REST services • Rave is a development platform • Developers program to Rave APIs and implementations as JARS, WAR overlays • Developers can change, extend, or exclude only the code without touching the source tree • “Sandbox” examples. 1
- 9. The Apache Way and Gateways • Apache places community above code – Open source isn’t enough – You need a diverse community of developers and inter-project collaboration • Governance – Apache incubators are mentored to teach good project management practices – Source code management, public mailing lists, open decision making, peer-reviewed formal releases • Sustainability – Apache incubators must demonstrate developer diversity – Count diversity of contributors, not downloads. – Reward projects for collaborating with each other. 1
