1. Cyberaide JavaScript: A JavaScript Commodity Grid Kit Gregor von Laszewski laszewski@gmail.com, (585) 298 5285 Fugang Wang http://www.cyberaide.org http://cyberaide.org16/1/2015

2. Outline Approaches to access the Grid -Infrastructure specific tools; middleware; portal Web 2.0 technologies applied to Grid portal -JSR 168 portal -Ajax, RESTful, RSS/ATOM, Mashup -A comparison The Cyberaide JavaScript framework -Introduction and architecture -A reusable JavaScript library; A portal Conclusion and discussion 6/1/2015http://cyberaide.org2

3. Approaches to Access Grid Grid Infrastructure - Condor, PBS, LSF, SGE - Globus, UNICORE, EGEE Upperware – Workflow tools with GUIs Many use cogkit.org – Portals Teragrid portal, Gridsphere, OGCE Many of them use cogkit.org Middleware/Upperware -CoG Kit (cogkit.org) -Cyberaide.org Gridshell (cyberaide.org) 6/1/2015http://cyberaide.org3

4. Portal technologies – JSR1686/1/2015http://cyberaide.org4 Java Portlet Specification (JSR168) Portlets Container Portlets Container Login Info FAQ Welcome Server Portlet Window Portlet Fragment Portal Server

5. Portal technologies – Web 2.06/1/2015http://cyberaide.org5 Web 2.0 technologies applied to web portals - Web 2.0, a buzz word. “Web as platform”? - Asynchronous JavaScript and XML (Ajax) - Representational State Transfer (REST) - Mashup - Atom and RSS

6. Portal technologies – Web 2.06/1/2015http://cyberaide.org6 …… Ajax - XML as data interchange medium - Asynchronous communication with server side - XHTML, CSS, and JavaScript to manipulate and render DOM components - Decrease user waiting time and increase user experience Static pages, CGI, Servlet Web page Web Browser Web Server Ajax engine JS code, CSS, libraries, web resources Rendered Web page

7. Portal technologies – Web 2.06/1/2015http://cyberaide.org7 REST/RESTful web service - Roy Fielding’s doctoral dissertation in 2000 - Resource = functionality + state - Unique addressable through URI for each resource - Use HTTP verbs such as GET, POST to do the CRUD operations (Create, Read, Update, Delete) - Eliminating the use of additional message layer such as SOAP or session maintaining cookies - Simplicity is beauty RSS and Atom - Web content publishing - Publish “feed”; Subscribe and read - Aggregating

8. Portal technologies – Web 2.06/1/2015http://cyberaide.org8 Mashup - Data from multiple sources - Mingle and combine - Presented in a new perspective Site A Site B Site C Web Service Web Client

9. Portal technologies – Web 2.06/1/2015http://cyberaide.org9 Mashup applied to JavaScript Grid Portal - Shows mashup happens both in server side and client side Teragrid Host A Teragrid Host B Teragrid REST Info service JavaScript CoG Kit service JavaScript API & Portal

10. Portal approaches: a comparison JSR168 Portal – Generate markup segments for each portlet and assembly them into a full page – Info aggregated at server side – Portlets displayed separately – Relatively old technology and is to be enhanced by newer standard (JSR286) Web 2.0 Portal – Combine raw data from different site/web services – Content aggregation can happen in server side or client side – Could combine data from different source and present in a totally new way – Web 2.0 technologies used to provide better user experience Web 2.0 Portal – Combine raw data from different site/web services – Content aggregation can happen in server side or client side – Could combine data from different source and present in a totally new way – Web 2.0 technologies used to provide better user experience 6/1/2015http://cyberaide.org10

11. A Web 2.0 Grid portal and reusable JavaScript CoG Kit Multi-tier SOA based framework Grid services are exposed through JavaScript library in client side for those web based Grid application developers A generic purpose Grid portal built upon the JavaScript CoG Kit enable access to Teragrid through web browser 6/1/2015http://cyberaide.org11

12. System architecture 6/1/2015http://cyberaide.org12

13. JavaScript Library enables Grid access JavaScript library to consume Java based web services while providing a higher level abstraction for web based Grid application developers JavaDoc style documentation - https://lily01.rit.edu:8443/grid/jscogdoc/jsdoc/index. html https://lily01.rit.edu:8443/grid/jscogdoc/jsdoc/index. html - Subject to change since it is still under active development Reusable to construct Grid portal or other domain specific scientific gateways upon it 6/1/2015http://cyberaide.org13

15. Teragrid Information Services 6/1/2015http://cyberaide.org15

16. Job Management 6/1/2015http://cyberaide.org16

17. File Transfer 6/1/2015http://cyberaide.org17

19. Conclusions and Discussion Road to Grid - Abstraction and reuse - More user-friendly and lower barrier - Less user involved setup and configuration - Architecture gets more complicated - Hide more complexity behind the “cloud” Trends - Service Oriented Architecture (SOA) / Web services - Software As A Service (SAAS) - Web application / Rich Internet Application - Cloud 6/1/2015http://cyberaide.org19
