Abstract
Introduction to Grid technologies
This introductory lecture provides an overview about Grid computing with respect to the general Grid vision, architecture, middleware, major infrastructures and applications as well as security.
Grid resource management, scheduling: concept and case studies
The lecture provides theoretical and practical aspects of Grid resource management including service discovery. Modern Grid infrastructures provide computing and storage resources and as well as other software services that are registered with Grid information services. High level Grid middleware can be used to interact with these resources to submit and execute CPU as well as data intensive applications. Specific examples will be based on the gLite and ARC middleware systems.
Scientific and Grid Workflow Management
Grid workflow management systems coordinate multiple job submissions over heterogeneous Grid resources. They feature visual programming environments to give scientist a high-level view over distributed computations composed of Grid services. This brief introduction to the field of scientific and Grid workflows includes a survey of selected workflow management tools and outlines current research trends.
