  1. GENIUS Grid Portal for e-Science community: a new experience for managing workflow in a SOA Livia Torterolo <livia@nice-italy.com> NICE srl EGEE’06 September 25-29, 2006, Geneva, Switzerland

  2. Scenario • Scientists have to execute complex tasks • There is the need to orchestrate these services in workflows Tools Storage and Data Services (SOA) Computational Power EGEE’06, September 25-29, 2006, Geneva, Switzerland

  3. Standard protocols Appl. Grid Portal / Gateway Gridified Scenario • Workflows based on Grid services • Providing optimisation, scalability, reliability, faul tolerance, … Tools Storage and Data Services (SOA) Grid Computational Power EGEE’06, September 25-29, 2006, Geneva, Switzerland

  4. Infrastructure proposal • Goal: proposal of a Grid-based solution able to provide the basic building blocks for composition and enactment of workflows for e-Science community • Tools: • EnginFrame or Genius: • As Grid services provider and Web interface for managing workflow • Taverna: • As Workflow designer • Moteur: • As Workflows enactor • Users can: • build workflows on top of exposed Grid services • run and monitor workflows via a standard Web browser • exploit in a transparent way the computational power and data access capabilities provided by the backend Grid infrastructure… EGEE’06, September 25-29, 2006, Geneva, Switzerland

  5. Web Portal WS provider MOTEUR (Scufl wf enactor) Services (SOA) The proposed Grid Infrastructure WSDL Tools Grid Portal / Gateway SOAP submit monitor Storage and Data gLite HTML/HTTP Computational Power EGEE’06, September 25-29, 2006, Geneva, Switzerland

  6. Grid portal Web interface The service interface implemented provides the following functionalities: • Upload of Scufl workflow and related inputs • Submission by Moteur • Monitoring of workflow • Results visualization EGEE’06, September 25-29, 2006, Geneva, Switzerland

  7. Test on a bioinformatics application • Implementation of a bioinformatics application workflow exploiting the proposed architecture • Based on DChip, one of the most complete and diffuse free software for the microarray data analysis • Composed of different modules: • data set opening and normalization • model based gene expression • extraction of differentially expressed genes • clustering EGEE’06, September 25-29, 2006, Geneva, Switzerland

  8. Application Workflow design EGEE’06, September 25-29, 2006, Geneva, Switzerland

  9. Scufl submission and enactment EGEE’06, September 25-29, 2006, Geneva, Switzerland

  10. Workflow status EGEE’06, September 25-29, 2006, Geneva, Switzerland

  11. Job details EGEE’06, September 25-29, 2006, Geneva, Switzerland

  12. Output Management EGEE’06, September 25-29, 2006, Geneva, Switzerland

  13. Conclusions and Future plans • Advantages provided by the introduction of a server-side component • Limits: Moteur appears as a performing enactor tool, but it imposes some limitations about processors and data inputs • Future steps: the proposed infrastructure is still a prototype. • Stay tuned on the evolution of MOTEUR… • Improve Web interface to provide users with dynamically generated forms for workflow inputs definition EGEE’06, September 25-29, 2006, Geneva, Switzerland

  14. A-WARE FP6 Funded Project • Project goals • Simplify users’ • life (focus on problems) • way of perceiving the GRID • Fill an existing gap • between middleware and portals • common interface to access gLite, Unicore/GS (DEISA project) and GT4 (TeraGrid project) • EnginFrame + A-WARE to be a completely integrated solution An easy Way to Access GRID REsources EGEE’06, September 25-29, 2006, Geneva, Switzerland

  15. Thanks for your attention! Q&A EGEE’06, September 25-29, 2006, Geneva, Switzerland
