6. Middleware Middleware combines multiple clusters together. – Administratively separate systems – Large dedicated clusters Globus Toolkit – Most popular of all Grid middleware technologies Developed at Argonne National Laboratory GT4 uses advanced WSRF Web Services G-Lite – Developed by the EGEE project – Used in the Large Hadron Collider experiments 11/9/2015http://cyberaide.org6

10. Introduction What is a System Shell? “A system shell is a piece of software that provides a text based interface which abstracts complex services for users.” 11/9/2015http://cyberaide.org10

11. Shell environments Shells are used to abstract complex services Typically used in Operating Systems Hide the complexity of the underlying kernel and support services Provide a unified user environment Command-Line Interface – To many power users, this is preferred – More function and control available Shells can be scripted to automate common high-level tasks. 11/9/2015http://cyberaide.org11

12. Shells used System Shells shkshbashzshcshrc Distributed Shells PdshPsshJXTA Aspect- Shell Language Shells Python CLI iPythonIRBBeanShellGroovysh System shells are used as part of an OS to provide a CLI for users Distributed Shells execute tasks similar to system shells, however in Parallel Language Shells interprets users’s code and commands during runtime System shells are used as part of an OS to provide a CLI for users Distributed Shells execute tasks similar to system shells, however in Parallel Language Shells interprets users’s code and commands during runtime 11/9/2015http://cyberaide.org12

13. Problem A steep learning curve and high entry barrier limit the use of Grid computing within the scientific community. – Parallel programming is difficult – Using middleware technologies can be cumbersome and inefficient – Users need to be advanced programmers just to use the technology How do we simplify the Cyberinfrastructure environment for scientists? 11/9/2015http://cyberaide.org13

14. Requirements Simple, intuitive, and user friendly Unifying framework Extensible Interactive Fault tolerant Event management Support batch processing Integrates new Cyberinfrastructure 11/9/2015http://cyberaide.org14

15. Rochester Institute of Technology What if we combined Grids with Shells? Performance + Usability (have your cake and eat it too) 11/9/2015http://cyberaide.org15

16. Cyberaide Shell Simple to use system shell which provides access to the powerful Grids and advanced Cyberinfrastructure that is available today However, “This isn’t your father’s UNIX shell…” 11/9/2015http://cyberaide.org16

20. Command List 11/9/2015http://cyberaide.org20

21. Nested Shells Cyberaide Shell supports the idea of Nested Shells – “shell-within-a-shell” – Each command has its own interpreter which interrogates options dynamically – More efficient scripts Two Ways: 11/9/2015http://cyberaide.org21

22. Literate Semantic Objects (LSOs) New data management concept LSOs store attribute-value pairs – simple! Mutable during runtime Object inheritance – All objects inherent form this object Can be recorded in many different formats – XML, JSON, CSV – Converted to SQL Provide semantic information to the shell during runtime 11/9/2015http://cyberaide.org22

23. Extending Cyberaide Shell Creating a Service Oriented Architecture Expose shell a Web Service – Web Services Interoperability standar – WS-Security for endpoint to endpoint security with X.509 certificates – Uses Apache CXF and Jetty HTTP server to host Web service Various Client API’s possible Using Web service, its possible to build a Web Portal on top of the shell! 11/9/2015http://cyberaide.org23

26. Future Work Implement other Cyberinfrastructure services – EGEE project and the Open Science Grid – Amazon Elastic Compute Cloud (EC2) Improve scheduling and workflow systems Improving integration with the Portal Develop language specific APIs 11/9/2015http://cyberaide.org26

27. Conclusion Cyberaide Shell helps scientists overcome the challenges faced when using advanced Cyberinfrastructure Combines the power of Grids with the usability of shells Enhances previous work in system shells with the use of semantic commands and nested commands Provides the shell as a Web service to allow for distributed usage across multiple platforms 11/9/2015http://cyberaide.org27
