Interoperability of Virtual Organizations on Complex Semantic Grid construction + grid Robert Balder OBERMEYER Planen+Beraten GmbH Munich, June 2005

Inteligrid target  Semantic grid  for Virtual Organizations  with focus on AEC

Contents  Where are we now?  Concerns about grid  What is a “nice to have”  What is really needed  User requirements

Where are we now?  No real grid running in construction  Server clusters for the CAD data  Project spaces for data sharing in Virtual Organisations  Special “grid-like” applications 

Concerns  Serious problems in the current IT structure  Viruses, Worms  Spam  This costs a lot of money  A grid is designed to do support remote processing and information sharing

Concerns  The opportunity of the grid is that we think about information sharing and remote processes when designing it

What is a “nice to have”  There are several areas where “High Performance Computing” would help  Rendering  Sonic computations  Special problems in static's  These are not the killer applications

What we need from a Grid  Sharing of data models and documents/plans is very complex  A project space is the right step, but still works with copies  A Semantic Project Grid for Virtual Organizations has a great potential  But don‘t forget the users...

User requirements  User types  „typical“ end user (Engineer)  Real Company CIO  VO Project Manager  Grid CIO

Typical industrial end user  Consider user interface  HPC  Storage, semantic data

User interface Space for semantic data

Company CIO/Sysad  Has to support one grid for every Virtual Organization  Responsible for  Loss of data  Quality of service  Long term data management

VO project manager  Setting up VO  Running VO  Terminate VO!  Responsible for?  Long term data management  Not only one VO

Grid CIO/Sysad  Setting up VO  Running VO  Terminate VO!  Responsible for?  Loss of data  Quality of service  Long term data management

Developer  IDE integration  Open grids or proprietary grids?  The best offer for software development will win

Conclusions  A semantic grid has the potential to take a key role in construction  Controlled information sharing is the „killer application“ for the grid  A VO grid corresponds to just one project, but there are more  Let the grid be as transparent as possible

Final remark  The ultimate killer application...  Let be successful The Extraterrestrial Intelligence should help us to solve our problems in
