DESCRIPTION
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

SCI-BUS is supported by the FP7 Capacities Programme under contract nr RI-283481 1
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

Projects and school program
SZTAKI Cloud (day 1 and 2)
SHIWA and ER-Flow(day 6)
SCI-BUS (Day 3-5)
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
