  2. Outline • Introduction • Objectives • VLAM-G Principles • VLAM-G Architecture • VLAM-G & DASII • VLAM-G Application Examples • Conclusions

  3. VLAM-GVirtual Laboratory AMsterdam A collaborative analysis environment for applied experimental science Grid and VLAM is about sharing resources: • physical equipment (remote experimentation) • Data & Information repositories

  4. Application Layer Virtual Lab. Grid Layer

  5. Objectives & realization Methods • Enable VLAM-G users todefine, execute, and • monitor their experiments • Provide to VLAM-G users: • location independent experimentation, • familiar experimentation environment • assistance during their experiments • Easy way to bring/port new/existing applications to the Grid • Developing application prototypes to check ideas and to learn

  6. Objectives & realization Methods • Application layer • Case studies • Provides VLAM-G modules • Middle layer (Top) • Hides the details of the Grid • Offers an information management system

  10. Process Flow Template(PFT) • Used as a blueprint for a specific type of experiments • PFT is designed offline by the experts in each scientific domain • It is the main interface used by the VLAM-G users to perform a specific experimentation in the VLAM-G environment. • It Guides the user while performing the experiment.
