1. Introduction to the program of the summer school Peter Kacsuk MTA SZTAKI kacsuk@sztaki.hu SCI-BUS is supported by the FP7 Capacities Programme under contract nr RI-283481 1

2. Who are the members of an e-science community? End-users (e-scientists) (50.000-500.000) Execute the published WF applications with custom input parameters by creating application instances using the published WF applications as templates WF Application Developers (500-1.000) Develop WF applications Publish the completed WF applications for end-users SG Instance Developers (50-100) Develop application domain specific SG instance Science Gateway (SG) Framework Developers (5-10) Develop generic SG framework

3. What do WF developers need? WF App. Repository Access to a large set of ready-to-run scientific WF applications Accessing a large set of various DCIs to make these WF applications run Local clusters Supercomputers Desktop grids (DGs) (BOINC, Condor, etc.) Cluster based service grids (SGs) (EGEE, OSG, etc.) Supercomputer based SGs (DEISA, TeraGrid) Grid systems Distributed Computing Infrastructure (DCI) Clouds Science Gateway (SG) framework Using a SG framework to develop applications and share them with others

4. What do e-scientists need? App. Repository Science Gateway (SG) instance E-scientists Local clusters Supercomputers Desktop grids (DGs) (BOINC, Condor, etc.) Cluster based service grids (SGs) (EGEE, OSG, etc.) Supercomputer based SGs (DEISA, TeraGrid) Grid systems Clouds Sharing ready-to-use appls via the repository Joint run appls via the gateway in the hidden e-science infrastructure Distributed Computing Infrastructure (DCI)

5. er What do we want to achieve? 5 Grid BOIN C Cloud Bio Che mist Phy sics Cyberspace Workflows Infrastructures Users should be able to access and use any WF and any infrastructure in an interoperable way no matter which is their home WF system Taverna Galaxy Kepler WF systems

6. er Grid BOIN C Cloud Bio Che mist Phy sics Cyberspace Workflows Infrastructures Taverna Galaxy Kepler WF systems Science Gateway Cyberspace access via gateway

7. er Grid BOIN C Cloud Bio Che mist Phy sics Cyberspace Workflows Infrastructures Taverna Galaxy Kepler WF systems Science Gateway Projects and school program SZTAKI Cloud (day 1 and 2) SHIWA and ER-Flow (day 6) SCI-BUS (Day 3-5)

8. Summary The 4 projects have created a technology that enables to combine many different WFs, WF systems and DCIs in many different ways with a gateway access It is like a puzzle where you can put together the required pieces to create the final picture 8 gUSE WF Engine OpenNebula Cloud Kepler WF gUSE gateway gUSE gateway Taverna WF
