Application development for the EGEE grid This talk sets the context of the session. It explores the challenges inherent in developing applications for Grids. It then reviews some of the functionality that was introduced in gLite 3.0 that is of particular significance to application developers. Finally an overview of the remaining practicals and talks is given.

Practical: Application development There are three sets of exercises in this practical. 1. More complex examples of Workload Management including use of a script to run several jobs. 2. Running an MPI job 3. Use of the GFAL library to access a file on a Storage Element

Data and metadata services This talk gives a brief reminder about the data services in gLite and then introduces the need for the AMGA service, to support metadata. This is used in a short practical.

What is happening in my jobs? Monitoring using R-GMA R-GMA provides information and monitoring services. It permits Grid users to share information in a virtual database. The concepts of R-GMA will be explained in a talk and in the first of two practicals. The second practical explores the use of R-GMA in monitoring applications.

A look to the future An introduction is given to OMII-Europe and ETICS, which are helping to set the context for future application development on grids. Initiatives towards application hosting environments and "service oriented research" are described.
