  7. K-Wf Grid - Objectives • To enable users to create complex workflows and use grid resources without detailed knowledge of grid • To construct workflows optimized for underlying infrastructure, using its advantages and avoiding its bottlenecks • To (semi-)automatically construct workflows based on user’s requirements, using semantic annotation of services, data, applications and resources • To constantly renew information about the grid by using complex monitoring network – to learn from experience • To provide simple, easy-to-use interface to K-Wf Grid services Dec. 4- 6, 2006, Amsterdam

  8. K-Wf Grid: Concept Execute workflow Monitor environment Construct workflow Analyze information Reuse knowledge Capture knowledge Dec. 4- 6, 2006, Amsterdam

  9. K-Wf Grid - Architecture User User interaction through the Portal Guidances for the user Knowledge Web Portal Grid Workflow User Interface User Assistant Agent Grid Organizational Memory Information on available resources and their description Workflow composition and execution visualization User’s decisions in crucial points of execution Ontological store of knowledge Workflow Orchestration and Execution Automatic Application Builder Workflow Composition Tool Analysed and extracted knowledge Information about workflow execution Scheduler PerformanceAnalysis KnowledgeAssimilation Agent Grid Workflow Execution Service Information about performance of particular resources Information about resources and environment Execution of chosen Grid services Low Level Grid Middleware (WS-RF) Grid Performance Monitoringand Instrumentation Service Grid Resources Dec. 4- 6, 2006, Amsterdam
