6 2. Goal A grid application developer has developed a new application that must be offered for other people through a Web-based portal which is highly customised for the application and the user community. People being offered with this service do not know grids but they should be able to execute the grid application with their own custom inputs through the graphical interface of the Web portal. Application specific portal Grid application developer End users

17 P-GRADE PORTAL 2.7 server Services of P-GRADE Portal (workflow management, parameter study management, fault tolerance, …) 7. Detailed Scenario Publisher Part of Application specific module Portlet to publish applications Registry of published applications EGEE and Globus Grid services (gLite WMS, LFC, …; Globus GRAM, GridFTP, …) Portal Administrator installs the P-GRADE portal 2.7. Then adjusts the portlet to publish applications, and installs the Application Specific Module for a special application. He/She has to know some information about the application eg. ProjectName, hierarchy of the packages... Then creates a new role for the Application. It has to be the same as the Name of the Project! Finally sends the modified source files to the Application Developer

18 P-GRADE PORTAL 2.7 server Services of P-GRADE Portal (workflow management, parameter study management, fault tolerance, …) 7. Detailed Scenario Publisher Part and the modified Application specific module Portlet to publish applications Registry of published applications Grid Application EGEE and Globus Grid services (gLite WMS, LFC, …; Globus GRAM, GridFTP, …) Grid Application Developer creates own Grid Application. Warning : Grid Application Developer has to be in role „Admin” too!!
